The introduction of the National Disability Insurance Scheme (NDIS) has significantly changed both the disability service and support sector, and disability housing landscape. Since the introduction of Specialist Disability Accommodation (SDA) funding to the scheme in July 2016, the SDA market has, and continues to, rapidly evolve and change. Unlike the service and support sector however, the SDA sector is not able to be as “…responsive to short-run changes in market dynamics” (National Disability Insurance Agency, 2020b) due factors such as relatively long lead times associated with the planning and construction process, and its fixed geographical nature - which limits its ability to meet changing geographical demand like other supports or services. For these, and other reasons, access to reliable data is a critical part of ensuring alignment between the supply and demand sides of the market.
