SIL vs SDA: What’s the difference, and which is in your plan?

Updated 22 May 2026 · reviewed by Prakash Bartaula, Founder, Novida

Supported Independent Living and Specialist Disability Accommodation are funded differently and do different jobs. Here’s a plain-English guide for participants…

Frequently asked questions

Does SDA pay my rent?
No. SDA funding goes to the dwelling provider as a contribution toward the cost of the specialist housing. Participants living in SDA still pay a Reasonable Rent Contribution from their income. The SDA payment covers the additional cost of providing specialist housing above what mainstream housing would cost.
Can I lose my SDA approval if the NDIS reviews my plan?
SDA is generally considered a longer-term funding commitment and the NDIS does not typically remove SDA funding without evidence of a significant change in need. However, your SDA design category could be reassessed if your functional needs change materially.
Is there a waiting list for SIL?
There is no formal central waiting list, but because SIL requires a provider to have capacity and a vacancy in a suitable arrangement, finding SIL can take time. Registering your interest with multiple providers and working with a support coordinator is the most effective approach.
Can I choose who I live with in a SIL house?
In shared SIL arrangements you may have some input, but ultimately the provider manages occupancy. Participants who want full control over their living arrangement and housemates often find that ILO or tenancy-based models better suit their goals.
