 We live in the age of big data. By some estimates, there will be more than 200 billion terabytes of data collected around the world by 2025. This valuable asset has the potential to deliver new and exciting insights into some of the greatest problems facing the world today. In the Australian health and medical research sector, gaining access to meaningful data has been an ongoing challenge. Welcome to the Hesanda program and Health Data Australia, where we are bridging the gap between data and discovery. Health Studies Australian National Data Asset, or Hesanda, is an initiative that makes health and medical research data easier to find. It facilitates access, sharing and reuse of research data. It aims to support improvements in researcher collaboration, opportunities to answer new research questions, more efficient and effective research to help improve health outcomes, and a reduction in research waste. The research community across Australia has been working together through Hesanda to develop the Health Data Australia catalogue, which allows health and medical researchers to register a description of their research or data set, also known as metadata, so it's easy for other researchers to discover. Hesanda is a federated structure of partners across Australia that links researchers together and facilitates data sharing and data access. This is possible through Health Data Australia, a searchable online catalogue and data request portal. To find out more on how you can share your research data and how we can help, visit our website.
