# SDA Signals

> The only independent NDIS Specialist Disability Accommodation (SDA) market intelligence tool in Australia. Provides demand vs supply analysis, investment signals, and design category breakdowns for every SA3 region — updated quarterly from official NDIS data.

SDA Signals helps property investors, developers, and advisors make data-driven decisions about where to build or invest in Specialist Disability Accommodation. All data is sourced from official NDIS SDA quarterly market reports. We are 100% independent — we do not sell SDA properties or manage investments.

Each of Australia's ~300-350 SA3 regions is classified with: total demand (participants eligible for SDA), total supply (places available), places gap, utilisation rate, a market assessment (Undersupplied Strong, First Mover, Undersupplied, Moderately Undersupplied, Balanced, Oversupply Caution), a confidence level (High, Medium, Low), and an investor action signal (Build Now, Good Timing, Land Bank, Monitor, Conditional, Cautious, Wait, Avoid).
