NDIS Provider Rankings by Trust Score

The NDIS Trust Index ranks 26468 registered NDIS providers across Australia by an objective 100-point Trust Score. Use the rankings below to compare providers on transparency, compliance history, regulatory standing, business legitimacy, and market signals. Every score is rebuilt monthly from public NDIS Commission, ABR, ASIC, and live web data.

What the Trust Score measures

The Trust Score is not a quality-of-care rating. It is a transparency and accountability signal, built from data the provider has chosen to make public and from records held by Australian regulators. Five components contribute to the final 0 to 100 score:

• Business Legitimacy (33 points): ABN age, GST registration, ASIC company status, name change history, banned director risk.
• Public Transparency (26 points): website presence, HTTPS, disability service keywords on the live page, contact channels, address type.
• Regulatory Standing (11 points): NDIS Commission registration status and any compliance action, sanction, or suspension on the record.
• Market Signals (20 points): number of registration groups, outlets, geographic footprint, market concentration in the local area.
• Integrity Signals (10 points): shell-company indicators, contact details shared with other providers, unusual service combinations, address co-location density.

How the bands work

Scores fall into five bands. Excellent (80 and above) means strong signals across every component. Good (65 to 79) is a solid provider with one or two soft signals. Fair (50 to 64) means several gaps worth checking before engaging. Poor (35 to 49) means significant transparency or compliance concerns. Providers below 35, or whose registration has lapsed, are flagged Not Operating. This covers deregistered, suspended, banned, voluntarily withdrawn, and ABN-cancelled providers. Not Operating providers stay listed so participants can verify the current status of a provider they were once with.

How this differs from the NDIS Commission register

The Trust Index is not the NDIS Commission's provider register. The Commission's register tells you whether a provider is currently registered to deliver NDIS supports, which is a binary yes-or-no answer. It does not tell you how long the underlying business has existed, whether the company's directors have a banned-officer record, whether the provider has been the subject of a compliance action, or how the provider compares with others in their suburb, LGA, or registration group. The Trust Index does. We pull from the Commission register, the Australian Business Register, ASIC's company and director records, and the live web presence of each provider, then we publish what those sources say, scored consistently across every provider in the country.

The Trust Index is also not a complaints register or a review site. We do not publish participant reviews. Every flag and every score is derived from a verifiable public source. If you see a score you believe is wrong, contact us and we will recheck the underlying data.

Top-line state of the market

Of the 26468 registered NDIS providers in Australia, roughly half score in the Good or Excellent bands, around a third land in Fair, and the remaining providers either score Poor or are flagged Not Operating. The largest single drag on scores across the market is web transparency: more than a third of providers have no live website, a dead website, or a website with no disability service content. The second largest is business youth, with a meaningful share of providers holding an ABN less than five years old, which sits below the threshold for full Business Legitimacy credit.

How to use the rankings

Filter the table by the characteristic you care about. Researchers can isolate providers with shared contact details to study market consolidation. Participants and plan managers can sort by score within a state to find higher-transparency options in their area. Regulators can filter by compliance action plus shared contact to identify potential phoenix patterns. Click any column header to sort. Export any filtered view to CSV for further analysis.
