SDA Signals analyses demand and supply data across all Australian states and territories using official NDIS quarterly data releases published by the National Disability Insurance Agency. Demand is calculated from SDA-eligible participants currently using and not yet using SDA. Supply is measured in registered SDA places and dwellings. Market assessments and confidence scores are derived using a conservative methodology that prioritises investor safety. This data is updated quarterly and does not constitute financial advice. Always conduct independent due diligence before making investment decisions.
