The SDA gap

9,014 people have been found eligible for Specialist Disability Accommodation and are not living in it: 35% of everyone assessed as needing it. This page explains what that means and shows where they are.

What the gap is

Specialist Disability Accommodation is housing the NDIS pays for. It funds the building, not the help a person receives inside it, and only a small group of participants qualify: those with extreme functional impairment or very high support needs. Just 3% of all NDIS participants have been assessed as needing it.

Everyone assessed as needing SDA is in one of two states. Either they are living in it, or they have been found eligible and are not. The second group is the gap.

It is not a queue. The NDIA publishes no waiting list and no waiting time, and being in this group does not mean a home is on its way. Someone can be here because nothing suitable has been built near them, because what exists locally is the wrong design category for what they were approved for, because the right dwelling exists and somebody else lives in it, or because they have been found eligible but do not yet have the funding in their plan.

Utilisation is the share of people with an assessed SDA need who are living in SDA. Nationally it is 65%. It varies from under a third to almost all, district by district, and the table below is the clearest view of that anywhere.

How the NDIA defines these two groups

Quoted in full from the note the Agency publishes beneath the table, rather than paraphrased. It is worth reading, because it says plainly that the NDIA cannot yet fully explain the gap either.

The number of participants with SDA in use are participants that have SDA funding in their latest plan and evidence of using SDA. Participants who are SDA eligible (SDA funding not yet in use) are either participants that have SDA in their latest plan and don't have evidence of using it, or participants who have been found eligible for SDA through the home and living application process who don't yet have SDA funding in their plan. Evidence of SDA funding in use is estimated based on SDA payments, SDA service bookings and address matching to an enrolled SDA dwelling. Future enhancements to the PACE system will allow for better tracking and an ability to better understand why participants may not be using SDA funding. There are a number of participants who were found eligible through the legacy CRM process that require further investigation.

Reading the district figures. The NDIA suppresses any district count under 11, publishing it as <11. Those cells appear here exactly as published, never as zero and never blank, and any total that includes one is marked to show it is a floor rather than an exact figure. Quarterly figures run from 30 September 2024 to 30 June 2026. Service districts are defined by the current address the participant resides in. 'Other' includes participants where the service district information is missing.

Two ways to read the gap

A raw count and a rate answer different questions, and they rank the country differently. The largest gaps are mostly in big districts, because more people live there. The worst rates are mostly somewhere else.

Largest gaps by headcount

Where the most people are waiting. This is a count, so populous districts lead it largely because more people live in them.

Lowest utilisation

Where the smallest share of people with an SDA need are actually in it. This is a rate, so district size does not flatter it. Limited to districts with 100 or more people in need.
