SDA is a range of housing designed for people with extreme functional impairment or very high support needs. SDA is designed to be more accessible for participants based on their disability related support needs. It assists participants to live more independently in their home and allows other supports to be delivered better or more safely.
SDA data project
The NDIA is working to improve the SDA data that it shares publicly through the SDA data project.
The project aims to improve accessibility and reliability of SDA data, support informed decision making, and guide providers and investors to address future SDA needs.
We're working with Finity Consulting to understand what SDA data is helpful to SDA providers, investors, participants and their families and carers.
As part of this project Finity consulted over 100 stakeholders for their insights.
Find out more about the SDA data project consultation.
The NDIA is also developing improved ways of collecting and sharing SDA data. This will help make SDA data more useful for participants, providers and the community. This includes the release of the Specialist Disability Accommodation Report (May 2025), in addition to continuing to enhance regular quarterly reporting. We will continue to enrich the information in these reports based on feedback we receive and as more improvements are made to how we collect and share SDA data.
