The University of Adelaide/Playford Trust PhD ScholarshipTroy Rogers, The University of AdelaideSource to sink – the connectivity of King George whiting in SA gulfsystems

The first component of my study aims to identify the number of spawning sources which contribute to the replenishment of the King George whiting (KGW) population within SA gulf waters.

I am currently employing an intensive field sampling schedule to investigate the temporal stability of population dynamics and otolith elemental chemistry throughout the KGW recruitment period. This involves towing a small net through shallow sub-tidal waters to collect recently settled KGW post-larvae.

I will have approximately 1,000 larval fish which are then dissected under a microscope to remove the otoliths. These tiny calcium carbonate structures assist with orientation and sound detection in fish, whilst also recording the daily environmental conditions encountered.

Movement throughout the fish’s life can then be reconstructed, enabling the spawning sources to be determined. Funding from the Playford Trust has facilitated the sampling of additional settlement sites, providing an extensive coverage of all recognised KGW nursery areas.

2016Playford Trust PhD ScholarshipNaomi Tucker, The University of AdelaideUnderstanding the Bunger Hills: key to the Proterozoic Australian-Antarctic connection

The Bunger Hills are the second largest ice-free area in the Australian Antarctic Territory, and provide excellent exposure of the East Antarctic Craton. Furthermore, the Bunger Hills occupy a critical position at the westernmost extent of the Musgrave-Albany-Fraser system that spans from central Australia into East Antarctica. This continent-wide system is broadly interpreted to record the amalgamation of the Australian-Antarctic cratons during formation of the supercontinent Rodinia (1.3–1.1 billion years ago). However, the geological significance of the Bunger Hills is, at present, not well understood. Discerning the crustal growth history of the Bunger Hills is therefore the current focus of my PhD.

From December 2014–February 2015 I had the immense privilege to undertake six weeks of remote fieldwork in the Bunger Hills as part of an Australian Antarctic Division funded science project. Results obtained to date from the sampled rocks reveal a previously unrecognised Archean-aged terrane within the Bunger Hills. Geochronology and isotope data also suggest that the Bunger Hills experienced a very similar Proterozoic tectonic evolution to that of southwestern Australia.

Regional Science and Engineering Scholarships

We asked our regional scholars about their challenges and the value of winning a Playford Trust scholarship.

Alice GoodfellowMy family and I live in the close-knit community of Streaky Bay, 900km SW of Adelaide on the Eyre Peninsula where I completed my primary and secondary education. One challenge that I faced is coming from a small school, where I was one of only twelve Year 12 students, to a large university and a course where I am one of hundreds.

The subject I have enjoyed the most is Microbiology, particularly relating to pathogens and bacteria. However, I have also discovered that I have a keen interest in both geology and ecology with their real-life relevance and application. Learning from my lectures about the research being conducted at The University of Adelaide has also been an interesting and enjoyable element of university life.

The scholarship has helped hugely by assisting with my financial independence. It has also benefited my parents and family, who know I can support myself without being wholly dependent on them.

Amelia MardonI am originally from Port Augusta, 300km north of Adelaide, where I attended Caritas College. I have always lived with my family, so moving away and living independently was my greatest challenge. I also found it difficult to maintain a balance between study, sport, social and other commitments as well as managing my finances. Being awarded the Playford Trust scholarship has been hugely beneficial for not only my studies but my transition to the city. It has eased the pressure of having to find a job immediately, therefore giving me enough time to settle in and get into the routine of life at university.

I have enjoyed studying biology and chemistry this year. After speaking with a course co-ordinator, I have decided to pursue medical research as a career. Although it will be a lot of hard work and dedication, it will be highly rewarding in the long run.

Bradley MartinMy family lives in the town of Naracoorte in the SE of South Australia, where I attended Naracoorte High School. Moving to Adelaide required me to adapt to a new environment and lifestyle as well as finding a means of financing my university expenses and accommodation costs. Winning the Playford Trust scholarship lifted some of the financial burden from me and gave me the opportunity to put more focus towards my study and adjusting to life in Adelaide.

So far I have enjoyed all the topics in my science degree, including opportunities to test my knowledge in a practical manner both in labs and out in the field. My dream career is working as a biologist, working with a variety of different organisms. The biggest challenge at university is the sudden independence and time management that I had to put in place – it was so different to high school. But I can now take advantage of the many choices available at university, enjoying both the social and academic activities on campus.

Laura ShroderI am honoured to have received the Playford Trust scholarship, it has greatly assisted in a smooth transition from my home town of Keith, where I attended Keith Area School, to Adelaide to study at Flinders University. Not having to worry about the extra costs associated with staying on campus has meant that I could be more focused on my studies, without the need for part-time work, giving me time to adjust to university life.

I am undertaking a Bachelor of Science in the High Achievers Program, where I am currently specialising in Biodiversity and Conservation. Having successfully completed my basic science topics last semester, I am now moving into introductory topics, which will give me an insight into whether I want to pursue a career in this area of science.

The High Achievers Program, has given me a great insight into different fields of science from guest lecturers about the different types of research projects being undertaken at Flinders. I thank the Playford Trust for its assistance as well as providing the opportunity to listen to some inspiring guest speakers at the awards night.

Josh Crilly Bachelor of Science Advanced, The University of Adelaide Brightness of the proton

There has been a lot of recent interest in Quantum Electrodynamics (QED) contributions to the proton’s structure, primarily driven by the 750GeV di-photon resonance at the Large Hadron Collider (LHC). Although the signal has now disappeared, it is still important to have a thorough understanding of the composition of a proton to understand the experimental results. This research has revolved around calculating the photon momentum fraction of the proton. In other words, how much of the proton’s internal structure is composed of photons (light).

This is being determined via two different methods. Perturbative Quantum Field Theory calculations are being performed to obtain the first-order contribution. In parallel, Lattice calculations combining Quantum Chromodynamics (QCD) and QED, are underway to obtain a non-perturbative result. The two methods allow a comparison and a greater understanding of the difficulties of the problem.

Daena HoBachelor of Engineering (Chemical Sustainable Engineering), The University of Adelaide Modelling of a novel solar thermal receiver

Renewable energy is globally recognised as the means to provide for the world’s energy demands while also mitigating further environmental damage. The primary obstacle in the uptake of renewables is the extreme variability in energy produced. Solar thermal concentrating solar power technologies (CSP) have potential to provide reliable and dispatchable energy that is compatible with existing energy infrastructure. However, CSP faces several technical challenges in up-scale and has a theoretical efficiency limit due to low operating temperatures. My research proposes a new receiver design that overcomes multiple technical challenges, has excellent up-scale potential and can operate at high temperatures, hence resulting in higher theoretical efficiency.

I am currently developing a mathematical model of the proposed receiver which will provide first-principles understanding of how the new receiver works and deliver a valid projection of its performance under varying operating conditions.

This research is significant because it serves as a feasibility analysis of the novel receiver design, which is extremely promising. It has the potential to provide one of the crucial bridging steps to enable CSP to deliver high renewable baseload power and transform the energy sector.

John McGuire Bachelor of Engineering (Mechatronic), University of South Australia Flight control design for a hybrid rocket engine with variable thrust magnitude and vectoring

Most regular missiles use fins and small deflections of these fins to turn, which makes changing course a relatively long process and restricts the missile’s ability to perform complex flight manoeuvres.

The goal of the project is to develop algorithms for controlling a hybrid engine rocket propelled by a novel adaptive thrust capability which can control both thrust vector angle and magnitude.

The difficulty in the problem comes with trying to control the entire motion of the vessel with only a single thrust vector and no other control inputs. This work will demonstrate that finless missiles can be controlled effectively in the earth atmosphere and that this new technology is a viable option for defence and civilian missile applications.

Liam Howard-FabrettoBachelor of Science, Enhanced Program for High Achievers, Flinders UniversityInvestigations into the gas-phase synthesis and electronic properties of ruthenium metal clusters

My research involves creating gas-phase metal clusters using a ‘cluster source’, and depositing them onto graphite surfaces. Such clusters have been shown to have different properties to a bulk metal, and are effective catalysts for many industry-relevant reactions. However, little is yet known about the electronic properties of these clusters, which are directly related to their catalytic abilities. My goal is to deposit ruthenium clusters composed of less than 100 atoms onto graphite, and then measure their electronic properties.

Initially clusters would not attach to any surface, however this was solved by using a higher flowrate vacuum pump. In optimising the cluster source to produce small clusters at a high enough rate, there are many parameters to adjust. A key step forward has been using liquid nitrogen to cool the gas, which greatly improved performance. Once clusters have been made with the desired size and surface coverage, their electronic properties will be measured using the techniques MIES and UPS. These measurement techniques work by probing the clusters causing electrons to be ejected, the energies of which are measured to give information about the electronic properties.

Stephanie MacWilliamsBachelor of Science (Advanced Materials), University of South AustraliaPrecursor film formation of imidazolium-based ionic liquids on layered minerals

Ionic liquids are a diverse group of salts made from large and asymmetric organic cations and smaller inorganic or organic anions. Unlike other salts, ionic liquids are liquid at room temperature as they cannot form a stable crystal lattice. Ionic liquids have potential applications as next generation lubricants and as electrolytes in energy storage devices. Central to their application in these two areas are their interactions with surfaces and substrates that are present in devices and machines.

One of the best ways to investigate how ionic liquids interact with surfaces is to study their wetting: how droplets of liquid spread on a solid substrate. The basic information obtained from such studies gives an indication of the affinity of the liquid for the solid. More complex information can be obtained by studying the molecularly thin layer of liquid that extends from droplets. We call this film the precursor film. My honours project will focus on using atomic force microscopy (AFM) to investigate the lateral extent and nature of the precursor films formed from three different ionic liquids on two different layered mineral surfaces: graphite and molybdenite. The underlying hypothesis of my project is that the extent and nature of precursor films can be controlled by altering the chemistry of individual components of the ionic liquid as well as the solid substrate.

Tenzin CrouchBachelor of Robotic Engineering, Master of Engineering (Electronic), Flinders UniversityDeveloping a deployable small unmanned aerial vehicle (UAV) for marine environments

Space is of great importance on marine craft and any equipment must be stored in a minimal size configuration. UAVs are an excellent tool for local area environmental monitoring and maritime surveillance operations. However, for these UAVs to be usable they must be capable of being stowed away.

This project investigates the possibility of developing a UAV which is not only small and stowable, but can also fly at low speeds for long durations, making it optimum for monitoring tasks. The project is currently in the second prototype stage with the first prototype showing promise but requiring improved aerodynamics. The next stages will be to perform flight tests on the second prototype and then to develop and test a launch system.

Robert TrottBachelor of Engineering (Mechanical), Master of Engineering (Biomedical), Flinders UniversityThe novel control of a unilateral exoskeleton for post stroke rehabilitation

Stroke is the leading cause of disability in the developed world. Walking, or gait, can be severely affected by stroke and has strong correlations to a survivor’s quality of life and their ability to participate in activities of daily living.

My project concerns the development of a novel control mechanism for a robotic exoskeleton with the aim of improving the outcome of gait rehabilitation for stroke patients. Robotic rehabilitation offers many benefits compared to traditional rehabilitation therapy, such as increased intensity and lower therapist workload. However, the level of recovery between methods does not differ significantly. By developing a novel control mechanism, and a prototype robotic exoskeleton on which to verify the concept, it is hoped that the user will have improved recovery beyond that which current rehabilitation achieves.

Jamee SeccafienBachelor of Science (Animal Science), The University of AdelaideThe effect of heat stress on porcine oocyte maturation, fertilisation and embryo development

My project is considering how heat stress affects porcine oocyte maturation, fertilisation and embryo development as well as considering natural supplementation methods to alleviate the negative effects. The first two months of data collection produced less than desirable results, which cannot be used for my final thesis.

This taught me a great deal about resilience and the importance of perseverance, as I was able to improve my results through altering a number of my experimental methods. The support from the scholarship allowed me to reduce my hours at my part time job to focus on improving my experiment. I am now pleased to say after four months of data collection I have successfully completed that portion of my Honours year. My final work will concentrate on the statistical analysis and writing-up my thesis.

Hayley PedlerBachelor of Engineering (Petroleum), Bachelor of Science (Geology and Geophysics), The University of AdelaideUsing reservoir simulation to investigate new drilling technologies for the Cooper Basin.

My Honours project involves investigating the feasibility of underbalanced drilling (UBD) in the Cooper Basin and is being undertaken in conjunction with Santos. UBD has been rarely applied in Australia, but can have advantages in both exploration and development stages of petroleum production. Notably, UBD prevents influx of drilling fluids into the formation, preventing formation damage and therefore improving reservoir capacity to flow. This can add incremental reserves and improve the Net Present Value, particularly in mature, low pressure fields.

This project involves simulation of a major Cooper Basin field, creating a dynamic reservoir model and then examining various scenarios. This will be used to investigate potential development options, including UBD. These insights may then be applied to other fields within the Cooper Basin, assisting with UBD candidate selection and helping to optimise development in one of South Australia’s most mature petroleum provinces.

Dion SamuBachelor of Chemical Engineering, Honours in Pharmaceuticals, University of South Australia

I relocated to Adelaide this year from my hometown of Whyalla where my family currently lives. Moving to Adelaide posed many challenges. I wanted to ensure that I started my first year of university with the best environment and support available, which ultimately led me to St Ann’s College.

Winning a Playford Trust scholarship supported by Chartwells and St Ann’s has assisted greatly with my move to the city by removing the financial stress. I have noticed this benefit throughout the year as I can focus solely on my studies.

Throughout my first year of university I have found the subjects of Chemistry; Biology: Molecules, Genes and Cells; and Biology: Human Perspectives, most enjoyable.

Once I complete my degree I hope to pursue a career within the pharmaceutical or nutraceutical industry. My interest in nutraceuticals is derived from my interest in health and fitness and I would enjoy being involved with the development and production of dietary and fitness supplements. The pharmaceutical industry also interests me as there is so much room for improvement within modern medicines and I would enjoy being involved with the development of new products that can be used to help people.

GSA/Playford Trust Honours Scholarship in Earth ScienceSamuel ConnellBachelor of Science (Geology, Applied Geology and Geophysics), The University of AdelaideFine-grained pyrite mineralisation in the Mount Isa copper deposit

The Mount Isa mineral deposit is a unique and complex mineral system, with both world-class deposits of lead-zinc and copper occurring within the same location. The deposit also contains abundant fine-grained pyrite mineralisation within the heart of the mining area. The timing of this mineralisation and its relationship to the ore system is important for working out how the deposit formed. The sulphide rich sediments containing fine-grained pyrite also create problems for drilling and explosive operations underground. This occurs through complex chemical reactions that release heat.

My project studied rocks rich in fine-grained pyrite using microscopy and geological modelling software. I aimed to analyse the structural and geological relationships of this mineral on both the micro-scale and deposit-scale. I also conducted reactivity testing on the sulphide-rich rocks with the aim of determining what causes reactive ground. This will help implement cost-effective safe management practices.

I thank the Playford Trust and the Geological Society of Australia for providing funding for my Honours work. Undertaking Honours in 2016 would not have been possible without this assistance.

Duncan FergusonBachelor of Engineering (Mechanical) Honours, The University of AdelaideCreating a new car for the Adelaide University Solar Racing Team

The Honours project in which I am involved is with the Adelaide University Solar Racing Team (AUSRT), which first competed in the Bridgestone World Solar Challenge (BWSC) from Darwin to Adelaide in 2015. The aim of the current team is to build a new car to compete in the 2017 BWSC. There are five sub-teams of Honours students working on the car, one of which is the High Voltage Electrical System team of which I am a member.

To date we have focused on the development of new encapsulation methods for the solar cells, as well as redesigning the layout and control systems for the car’s battery. This project has been highly rewarding and though challenging, it has broadened my knowledge of both mechanical and electrical engineering. It has also helped me to develop a greater understanding of how to engage sponsors, to network, and to successfully work in a large team.

Inaugural OZ Minerals/Playford Trust Minerals Industry Honours ScholarshipAlexandra SchemeczkoBachelor of Engineering (Honours) (Chemical), The University of AdelaideEstablishing the best microscope to characterise the minerals in a copper concentrate species

The aim of the project is comparing a range of highly powered microscopes to deduce, which will be the best to characterise the minerals in a copper concentrate species. The automated techniques to be reviewed include Mineral Liberation Analysis (MLA) and Quantitative Evaluation of Mineralogy via Scanning Electron Microscopy (QEMSEM). The manual ‘grain by grain’ approach is being completed on an Environmental Scanning Electron Microscope (ESEM).

To date, 51.5 hours of ESEM work has been completed, which includes 11 hours of training in the use of the microscope and mineral identification. The project is on track to be completed by the end of the year. I am grateful for the support of OZ Minerals, which has allowed me to visit their site, providing a valuable experience which has enabled me to gain a better perspective of the overall project.

Inaugural Fay Fuller Foundation/Playford Trust Honours Scholarship in Health ScienceElizabeth BennettBachelor of Clinical Sciences (Honours) at Flinders UniversityExamining and quantifying gender differences in diet

Poor diet is now the leading risk factor for death and disability worldwide. Given the rise in diet-related conditions, such as cardiovascular disease, diabetes and obesity, targeted action on unhealthy food choices is needed. It is known that women and men have different dietary habits, but there is not currently a gender-specific approach to nutrition policy and dietary interventions.

The aim of my research this year has been to explore, in detail, gender differences in dietary intakes to see if our approach to improving diet should be different for women and men. This project has taken me to the University of Oxford where I have been fortunate enough to analyse information about diet from a large dataset of over half a million people. The Fay Fuller/Playford Trust Scholarship has been invaluable in allowing me to pursue such an exciting and rewarding project, and I hope this knowledge can be used to improve the diet and health of South Australians.

SA Power Networks/Playford Trust Scholarship Vaishali GhoshBachelor of Electrical and Electronic Engineering, The University of AdelaideEnsuring communications on the battlefield

I am in my final year of the Bachelors of Electrical and Electronic Engineering and this year has been a very steep learning curve. It began with me being a successful recipient of the SA Power Networks/Playford Trust Scholarship and then I was selected to work on a sponsored project by the Defence Science and Technology Group (DSTG) called ‘Airborne Antenna measurement Platform’, for my Honours project.

This project is aimed at devising a 3D drone-mounted system capable of taking antenna radiation pattern measurements. This has wide application in defence where strong communication channels become essential, especially in the battlefield. This novel way of carrying out measurements will allow outdoor and in-context data gathering to map the real world characteristics of antenna beam formation.

Playford Trust events have been a great networking platform to meet industry representatives and Playford Trust Scholars. Thanks to a Playford Trust reference, I was offered work experience at WSP | Parsons Brinckerhoff as an Electrical Intern while I worked towards completing my undergraduate studies. This was a great opportunity as I was able to practically apply the knowledge gained at university to real world problem solving.

AusIMM/Playford Trust Honours Scholarships in Geoscience, Mining Engineering andChemical Engineering

Shaun O’Brien (far right)Geology(Honours), The University of AdelaideStructural and mineralogical controls on the formation of the inter-lens at the Ernest Henry Mine, Queensland

The Ernest Henry copper-gold mine is located 35km north east of Cloncurry in north western Queensland. A poorly mineralised structure named the ‘inter-lens’ exists as a shear zone within the copper-gold ore-body which effectively separates the ore-body into two distinct lenses. The inter-lens has not been examined previously and this project will study and characterise the feature by logging drill core with an aim to identify host rocks and describe veining and mineral relationships within the host rocks. Structural measurements and rock samples will also be collected underground where exposures of the inter-lens are located. Eventually this project will reveal whether the inter-lens shear zone is a relatively late feature, or was present prior to the formation of the ore-body. Results of this research have potential implications for mineral exploration models in the Cloncurry mineral district.

Scholarship partner AusIMM has offered a wide range of opportunities to develop my technical skills, with the Adelaide branch hosting numerous technical meetings. Playford Trust scholars were given an opportunity at the August technical meeting to introduce their projects and discuss their progress with an audience of industry professionals, which was greatly appreciated.

Tao YanBachelor of Engineering (Mining Engineering), The University of AdelaideThe effect of loading rate on rock mechanical properties

Loading rate describes the frequency of vibration. It commonly occurs in mining environments and it can change the mechanical properties of rocks. Stability is often analysed under a static condition. In reality, these conditions could change under vibrations. This problem is often overlooked.

The aims of this research are to find out the effect of loading rate on rock mechanical properties (peak strength, Young’s Modulus, cumulative strain and Poisson’s ratio) and develop corresponding models.

Rock samples are compressed to fail both cyclically and monotonically with loading rates from 0.0002 mm/min to 30 mm/min. A pre-monotonic loading is applied before the main test to create a reference point. In monotonic loadings, we compare the behaviour of pre-monotonic loading with the main test. In cyclic loadings, we compare the behaviour of first cycle with last cycle. We discovered that a higher loading rate is more likely to have a positive effect on the stability of a rock mass, because rocks will fail at higher stress, become stiffer and able to deform more laterally. However, once the rock reaches its limit, the failure will be more abrupt and explosive.

Christos KarageorgosBachelor of Engineering (Chemical-Minerals Processing), The University of AdelaideInnovation in minerals processing: predicting metallurgical performance

It is known that the metallurgical performance (concentrate grade, mineral recovery and selectivity) are all related to the mineralogy of the ore being treated. It is also understood that the pulp chemistry of the system is driven by the mineralogy. So, it should be possible to link the pulp chemical parameters to the metallurgy of a known system, then potentially use these parameters to predict the concentrate grade and mineral recoveries for unknown systems.

This project uses data collected from over 100 different copper ores from around the world to establish the connections between feed mineralogy, oxygen demand and extractable metal ions (ie. copper and iron), and the metallurgical response of these ores. Once the relationship(s) have been established they will be applied to a new sample to determine the validity of the correlation.

Scantech/Playford Trust Honours Scholarships in PhysicsHelen GengBachelor of Science (Honours) in High Performance Computational Physics, The University of AdelaideUsing stochastic techniques to improve numerical simulations in lattice quantum chromodynamics

Much of my research this year has been focused on learning the principles of the theory of the strong force known as quantum chromodynamics and how to simulate the physics using numerical and computational techniques.

I have gained a great understanding of the code underpinning the numerical simulations throughout the year and I have used stochastic techniques developed by the researchers at The University of Adelaide to calculate one of the building blocks used in lattice calculations: the quark propagator.

The results have shed some light on the best ways to generate the quark propagators and can be used as a stepping stone to investigate more complicated phenomena on the lattice such as multi-particle states.

Jake GuscottBachelor of Science (Advanced), The University of AdelaideDeveloping stricter statistical tests for more accurate mathematical modelling

The test statistic of a goodness-of-fit test allows us to evaluate how well a mathematical model fits a data set. Often our goal is to determine how likely it is that the given data set was drawn from our model.

To do this we must draw a series of points from our known distribution and determine the test statistic. Repeating this process many times allows us to understand the spread of these values.

In my research, we are determining the test statistic which corresponds to 95% confidence in the data being drawn from several common distributions. This research will allow for more accurate modelling and our group is hoping to implement the results into statistical software packages upon completion of my project.

Cell Therapy Manufacturing/Playford Trust PhD ScholarshipsAnouck BurzavaUniversity of South AustraliaProgenitor cells and stents: a more sustainable pathway for sufferers of cardiovascular disease

Cardiovascular disease is the leading cause of death worldwide, with coronary artery disease being the condition of highest prevalence. Once a complete blockage occurs in the blood vessel, a small mesh tube (stent) is implanted within the affected artery to restore blood flow.

Bare metal stents have been used for 30 years, with 26,000 being fitted in Australia during 2015 alone, at a procedural cost of approximately $18,300. A subsequent clot formation can leave a patient with a 20-40% chance of losing their life, while a more common ‘re-narrowing’ of the arterial pathway will also lead to further surgical intervention. An ideal stent should exhibit a biocompatible interface capable of preventing such complications. My research aims to develop a low-fouling and cell-selective stent coating to aid the reformation of the blood vessel lining.

Working with the Cell Therapy Manufacturing CRC has provided crucial support, allowing my research to focus on a direct industrialapplication with a leading medical device manufacturer.

Zaheri MahmudUniversity of South AustraliaNanophotonic biosensors for mycoplasma detection.

Mycoplasma bacteria are common contaminants of biological manufacturing processes. Conventional detection methods are hindered by long assay times, high costs and a requirement for trained personnel to perform these assays. Thus, there is a growing need for small, fast, efficient and portable biosensors. The aim of my research is to develop a photonic biosensor able to detect mycoplasma contamination with high sensitivity and specificity. The aim is to integrate the sensor into a simple and affordable device which will be capable of being employed at the point of use, during therapeutic cell expansion.

Partnership with the Cell Therapy Manufacturing CRC will provide access to the opinions of leaders in the cell therapy and biologics manufacturing industry, enabling implementation of a better device.

New Website for Playford TrustThe new Playford Trust website was recently completed. Our thanks to Richard Wallace of Wallace Web Design and Felicity Playford of Playford Learning Design. Richard and Felicity worked closely with our website sub-committee to develop a sophisticated design that reflects the history of the Trust and its vision for supporting the studies of high achieving South Australians. While the web design looks deceptively simple, it is intuitive to navigate for users and is also built to be easy to update and manage. Felicity Playford, who is Sir Thomas Playford’s grand-daughter, said that she was pleased to be able to work with a group of people who are as passionate about development opportunities for South Australia as was her grandfather.
