Accommodation (SIL/SDA) in South Australia

What accommodation (sil/sda) actually covers

Two different things that often get confused. Supported Independent Living (SIL) is the staffing, meaning the people who help you in your home, including overnight. Specialist Disability Accommodation (SDA) is the building itself, funded only for people with extreme functional impairment or very high support needs. You can have SIL without SDA, and different organisations often deliver them.

How it's funded

SIL sits in Core Supports and is quoted from a roster of care shared across the people in a home. SDA is a separate capital budget paid to the housing provider. SIL is one of the largest costs in the scheme, so it also draws the most scrutiny. Expect detailed questions at plan review.

What to know in South Australia

SDA in South Australia sits mostly in Adelaide, with limited stock in the regions. South Australia has been rolling out its NDIS Restrictive Practices Authorisation Scheme in stages, introducing an Authorised Program Officer and a Senior Authorising Officer to review applications to use restrictive practices. If the home you are considering uses any, ask which stage of that scheme applies and who signs off at the moment.

Choosing between providers

From 1 July 2026, SIL providers must be registered with the NDIS Commission, and the SIL Practice Standards apply. If a provider offering SIL is not registered, ask them why.

Questions worth asking

• Who else lives in the house, and can I meet them before I decide?
• What is the staffing overnight, awake or sleepover?
• What happens if I do not get on with a housemate?
• Is the SDA provider the same organisation as the SIL provider?
• If I want to move out, what is the process and how much notice do I give?
