Ranked by SDA Opportunity Index™ score (0–100). Higher scores indicate stronger demand relative to existing and approved SDA supply. Scores are recalculated quarterly using NDIS participant data, registered SDA stock counts, SIL provider density, and development pipeline activity.

Oversupply Warning: Avoid These Suburbs
The following suburbs are showing clear SDA oversupply as of Q2 2026. Existing registered SDA stock significantly exceeds current NDIS participant demand, resulting in tenanting timelines of 9–18 months. Investors should avoid new SDA builds in these areas until supply normalises: Logan QLD (Score: 38), Springfield QLD (Score: 31), Ipswich QLD (Score: 33). The wider South-East Queensland corridor requires suburb-specific analysis before any commitment.
About the SDA Opportunity Index™
The Opportunity Index™ scores suburbs from 0–100 across four weighted dimensions: NDIS participant demand density, existing and approved SDA supply levels, Supported Independent Living (SIL) provider density, and development pipeline risk. Data is sourced from NDIS quarterly participant reports, the NDIS Provider Register, and state planning registers.
Scores above 70 indicate strong demand-supply imbalance in favour of new SDA investment. Scores below 45 indicate risk of oversupply or insufficient participant base. Full methodology →
