Whole genome sequencing (WGS) is a new and powerful way of looking at a person’s DNA — the instructions that tell our bodies how to grow, develop, and function.
This technology can help doctors find the cause of certain health conditions faster and more accurately than ever before. In the future, it could help more people get the right diagnosis and treatment sooner, and even help prevent some illnesses before they start.
The Opportunity
Genomics is changing how healthcare is delivered around the world. South Australia has an opportunity to lead the way in using whole genome sequencing to improve care, speed up diagnoses, and provide more certainty to patients and families.
By preparing now, we can make sure these technologies are introduced in a safe, fair, and effective way that benefits everyone.
Our Approach
The Clinical Genomics Statewide Clinical Network (SCN) is working to ensure South Australia’s health system is ready to use whole genome sequencing on a broader scale.
Some of the key areas of focus include:
- Making sure everyone in South Australia can access genomic testing if they need it
- Supporting doctors, nurses, and other health professionals to learn how to use genomic testing and information in patient care
- Providing advice to the health system about how and where genomics can make a difference
- Collaborating on research and innovation to support the safe and effective use of genomics in clinical care.
Our Partners
This work is only possible through collaboration. The Clinical Genomics SCN works closely with:
- SA Health and Local Health Networks
- Researchers and academic partners
- Clinicians, genetic counsellors, laboratories, and diagnostic services
- Consumers, families, and community groups.
Together, we are building a health system that is ready for the future of personalised care.
Current Activities and Outcomes
What do people think?
Initial consumer testing on a small group of people from a diverse range of backgrounds has been carried out to understand how the community – including parents, potential parents, and others – feel about using genome sequencing in newborns.
The results showed that most participants were supportive of an approach where genomic information is collected early in life and made available to guide medical care if and when it’s needed, and believed the benefits outweighed the risks. People recognised the potential for earlier detection of serious conditions and were open to approaches that allow genomic information to be used when it’s most relevant to patient care.
This feedback is helping guide how information is shared with parents and how the health system can support informed, confident decision-making.
Understanding the costs and benefits
Whole genome sequencing is a powerful tool — but it’s important to understand whether the benefits are worth the investment, and how it can be used in the most effective and sustainable way.
An economic evaluation is helping to explore:
- The costs and benefits of different models of care, including a “sequence and store” approach where the genome is sequenced once and stored for future clinical use
- Whether this approach can reduce the need for repeated or unnecessary tests over time
- How early access to stored genomic data could lead to faster diagnosis and more targeted treatment when it is needed
- The potential long-term savings to the health system through more efficient care and better health outcomes
- The broader benefits for individuals and families, such as fewer delays, more certainty, and greater confidence in care decisions.
This analysis will help health leaders and policymakers make informed decisions about when and how genome sequencing should be used to provide the best value and impact for South Australians.
Linking to precision medicine
Whole genome sequencing is a key part of the broader move toward precision medicine — an approach to healthcare that tailor’s prevention, diagnosis, and treatment to an individual’s unique genetic makeup, environment, and lifestyle.
This work aligns closely with the CEIH Precision Medicine Blueprint https://ceih.sa.gov.au/our-work/precision-medicine, which outlines a roadmap for integrating precision medicine into South Australia’s health system. By building strong foundations now, the Clinical Genomics SCN is helping pave the way for a more personalised, data-driven, and equitable future in healthcare.
