Specialist Disability Accommodation (SDA) is one of the most misunderstood asset classes in Australian property in 2026. Done well, it sits in a unique sweet spot: long-duration tenanted income, strong social impact, and material capital growth potential. Done poorly, it underperforms quickly. This primer from Nexus Developments — operator of Nexus Care — covers the difference.

What SDA actually is — the basics
Specialist Disability Accommodation (SDA) is the housing pillar of the National Disability Insurance Scheme (NDIS). It funds the high-cost capital component of housing for people with extreme functional impairment or very high support needs. Importantly, SDA is housing only — it sits alongside Supported Independent Living (SIL), which is the funded support inside the home. Most SDA tenants live with a small number of co-residents and a 24/7 support team.
Why this asset class exists in Australia
Until SDA, Australia did not have a sustainable funding model for high-needs disability housing. The result was a chronic undersupply of accessible, dignified accommodation — and a significant cohort of people stuck in inappropriate aged-care or hospital settings. SDA was designed to close that gap by attracting private capital into purpose-built, well-located, well-designed disability housing. It is legislated through to 2029 and beyond, and identified by Government as a priority housing response.
How SDA economics work — RRC, SDA payment, capital growth
- Tenant pays a Reasonable Rent Contribution (RRC), typically based on a portion of the Disability Support Pension
- SDA payment from the NDIS supplements RRC to fund the capital cost of the dwelling
- Payment level depends on design category (Improved Liveability, Fully Accessible, Robust, High Physical Support) and location
- Asset is held long-duration; rental yield and capital growth are typically modelled separately
- The 2025-26 SDA pricing arrangements ran from 1 July 2025 with a 3.95% uplift across most rates — current through to mid-2026
The four SDA design categories and what they pay
Improved Liveability
Reasonable level of physical access for participants with sensory, intellectual or cognitive impairment. Lower payment rate.
Fully Accessible
High level of physical access for participants with significant physical impairment. Mid-range payment rate.
Robust
Resilient, reduced-risk environments for participants with complex behaviours. Mid-to-high payment rate.
High Physical Support
High level of physical access plus assistive technology integration for participants with very high physical support needs. Highest payment rate.
Ashburton, Nexus Care’s flagship Melbourne project, is positioned in the High Physical Support category.
Why location is the second-most important decision
Tenant retention, support-worker satisfaction, and family confidence are downstream of location. Inner-metro locations close to health services, accessible transport, family networks and quality retail typically support better tenant outcomes than outer-metro corridors with weaker daily-life infrastructure. The reverse is also true: outer-metro corridors with weak operator economics can leave SDA assets vacant for extended periods, regardless of how well-designed the building is.
Where most Australian SDA investors go wrong in 2026
Treating SDA as a yield play. The Australian SDA market through 2025 saw rapid supply growth in some outer-metro corridors — particularly Melbourne’s west (Tarneit, Truganina, Werribee) — leading to occupancy challenges as supply outpaced tenant demand in those specific submarkets. The lesson is not that SDA is a bad asset class. The lesson is that SDA is a long-duration tenanted asset class, with operational complexity, and the wrong design specification or wrong location can put an asset into a low-utilisation state for an extended period. Yield does not come out of an empty unit.
“SDA is a long-duration asset. Long-duration assets reward long-duration thinking.”
How Nexus Developments approaches SDA investment
- Design that treats accessibility as a default — not a feature
- Locations close to families, accessible transport, services and healthcare — inner-metro Melbourne preferred
- Operator partners with track record across SIL and tenant placement
- Conservative occupancy assumptions — Nexus Developments models the long stabilised case, not the launch case
- Long-duration capital structure that does not force a fire sale
- Governance and reporting framework consistent with the rest of the Nexus Developments portfolio

Frequently asked questions
What is NDIS SDA?
Specialist Disability Accommodation (SDA) is the housing pillar of the National Disability Insurance Scheme. It funds the capital cost of purpose-built housing for participants with extreme functional impairment or very high support needs.
Who pays the rent in SDA?
SDA tenants pay a Reasonable Rent Contribution (RRC), typically based on a portion of the Disability Support Pension. The NDIS SDA payment supplements RRC to fund the capital cost of the dwelling.
Is SDA a good investment in 2026?
SDA is a long-duration tenanted asset class with strong fundamentals when design, location and operator partner are selected well. It is not a yield play. Outcomes depend on specific project, location and capital structure. Speak to Nexus Developments for project-specific information.
What are the four SDA design categories?
Improved Liveability, Fully Accessible, Robust, and High Physical Support. Each has different design requirements and a different SDA payment rate.
How is SDA priced in 2026?
The 2025-26 SDA pricing arrangements run from 1 July 2025 to 30 June 2026, with a 3.95% increase across most SDA payment rates over the prior year. The NDIS reviews pricing annually.
Where can I invest in SDA via Nexus Developments?
