About this dataset

About 510 council areas (councils with fewer than 11 participants are suppressed), all 8 states and territories, and Australia; quarterly from October 2021 (December 2021 quarter-end) to April 2026 (June 2026 quarter-end). Period is the first day of the quarter. Current to 2026-06-30; refreshed quarterly.

What it is

A quarterly count of active NDIS participants (people with an approved disability support plan) by where they live, for every council area, each state and territory, and Australia, from the December 2021 quarter to the June 2026 quarter (19 quarters).

What it shows

For each area and quarter, how many residents are NDIS participants at the end of the quarter. Period is the first day of the quarter, so the June 2026 quarter is 2026-04-01. Watch the series to see how fast the scheme is growing locally: nationally it rose from about 502,000 to about 782,000 participants over the window.

Why use it

The NDIS is the biggest driver of disability housing and support-worker demand in Australia. A large or fast-growing participant base points to demand for specialist disability and supported accommodation, accessible rentals, therapy and support businesses, and local care jobs. Use it to size a disability housing or care-services opportunity in a council area, compare regions, or add a disability-support panel to a council or state report.

How it is built

We take the scheme's published quarterly counts of active participants by the council area of their home address and match each area to our council names. Counts below 11 are suppressed at source for privacy, so very small councils return no value for some or all quarters rather than zero. Council areas follow one fixed boundary edition across all quarters, so the series is comparable over time; councils renamed or merged since then are matched to our current name where they are the same area. State and Australia figures add up every participant in the state, including the few whose address could not be placed in a council area, so the council areas of a state add up to slightly less than the state figure. Participants are counted once, at their home address; this is a count of people, not of funding.

Fields
