Support Coordination for SIL and SDA Housing Transitions
How support coordination for SIL and SDA works: split the funding, prove SDA eligibility, manage conflicts of interest and land a clean housing move.

Frequently asked questions
What is the difference between SIL and SDA in the NDIS?
SDA (Specialist Disability Accommodation) funds the physical dwelling and sits in the Capital budget, paid to the property owner. SIL (Supported Independent Living) funds the support hours delivered inside the home and sits in the Core budget, paid to the support provider. They are quoted, decided and paid separately, and a participant often has two different providers for each.
Can a support coordinator recommend a SIL or SDA provider they are linked to?
Only with full written disclosure of the relationship and genuine alternatives presented, so the participant keeps real choice and control. The NDIS Code of Conduct and conflict-of-interest rules require this, and the NDIA is actively scrutinising SC invoicing in linked SIL and SDA arrangements. If you cannot present a real alternative, refer the housing decision to an independent coordinator.
How does a participant qualify for SDA?
SDA is for participants with extreme functional impairment or very high support needs where specialist housing is the reasonable and necessary response. It requires strong evidence, typically an OT housing assessment showing why lower-cost options cannot meet the need, plus a housing goal in the plan. The NDIA then decides eligibility, the design category and the building type the participant is funded for.
Does mandatory registration for SIL providers affect support coordinators?
Yes, indirectly. From 1 July 2026 SIL providers must be registered, so the SIL providers you coordinate with need to hold registration — check their status before facilitating a placement. Support coordination itself is excluded from this first registration wave, though standard SC registration requirements will align to the commissioned model from 2028.
Should the SDA tenancy and the SIL support be with the same provider?
Keep them separate wherever possible. A separate tenancy or occupancy agreement protects the participant's home if they later change support providers, preserving choice and control. Bundling the two can trap a participant in a poor placement, which is a common transition failure point.
