Find where SDA demand outpaces supply
Every region in the NDIA’s SDA demand data — 88 SA4 regions plus state-level ‘Other’ areas — is scored on the gap between eligible NDIS participants awaiting SDA and the dwellings currently enrolled, minus penalties where existing stock is sitting under-used or a new-build supply wave is still being absorbed. A big paper demand gap is not an opportunity if the dwellings already there can’t find tenants.
Score v2 composite: unmet demand 40 + supply gap 30 + market scale 15 + state demand momentum 15, minus up to 25 for stock saturation and 15 for new-build pipeline pressure. Every region also carries an explicit vacancy-risk rating and a design-category balance, so you can see not just where to build — but what to build, and where not to.

?How the score is calculated
+40
Unmet demand ratio
Unhoused participants ÷ total with SDA need
+30
Supply gap
Need minus estimated resident capacity of enrolled stock (dwellings × national residents-per-dwelling)
+15
Market scale
Log-normalised absolute unhoused count — larger populations score higher
+15
Demand momentum
State SDA participant growth, latest year — full points at 15%+ YoY
−25
Saturation penalty
Stock utilisation below the national norm — dwellings enrolled but sitting under-used
−15
Pipeline penalty
New-build share of stock above the national 72% — a supply wave still seeking tenants
Score v2 (July 2026). Penalties apply only to regions with 5+ enrolled dwellings — smaller stock can’t be read for utilisation. Utilisation compares each region’s residents-per-dwelling to the national average (≈1.18); it is a proxy, not a direct NDIA vacancy measure. All inputs from the latest NDIA quarterly SDA supplement.
