The National Disability Insurance Scheme (NDIS) provides individualised support to people with disability and is administered by the National Disability Insurance Agency (NDIA), a statutory agency of the Australian Government. 

In 2024 the NDIA supplied the AIHW with five limited NDIS content tables for inclusion in the National Health Data Hub (NHDH), establishing the infrastructure and governance arrangements required for managing NDIS information. In 2025 a formal data-sharing arrangement was established through an Exchange of Letters for ongoing data sharing from NDIA to AIHW to establish a comprehensive collection of NDIS data managed by the AIHW Disability Unit. This establishes AIHW to manage the data on behalf of the NDIA as custodian, including integration into the NHDH.  This expanded collection of tables replace earlier versions and provide a new baseline for integration, longitudinal analysis and reporting within the NHDH.

Data scope 

Content data is collected by the Commonwealth to administer the NDIS and covers the following components:


  • Access requests which contain history of applications for the NDIS, including dates, status of the application and decisions regarding the application.  
  • Early Childhood Early Intervention (ECEI) gateway which summarises children in the NDIS (under age 9 as of 2023) who enter the Early Childhood Early Intervention system, as well as the types of support used.  
  • Mainstream Interfaces describing the intersection of other known mainstream services i.e. Other government systems providing services to the Australian public, e.g. health, mental health, education, justice, housing, child protection and employment. Most people interact with a range of services throughout their lives. 
  • Participant Demographics which include information on NDIS participants, including age, gender, primary and secondary disability types, impairment, ethnicity, and geography of residence. It may also include information on people who apply for the NDIS but have not been approved.  
  • Payments which describe the history of services funded by participant’s NDIS budget, including rich detail on the type of support paid for. 
  • Plan Supports which describe the history of participants’ plans and the categories of support that the participant is permitted to spend their NDIS budget on.  
  • Carer Demographics which contains core demographic attributes (e.g., age, sex, relationship to participant, geography) for each registered NDIS carer. 
  • Early Childhood Approach (ECA) capturing ECA pathway records for children under 7, listing referral details, eligibility decisions, support outcomes and milestone dates 
  • Goals which lists each participant’s NDIS plan goals and capturing goal category, progress status, and key creation/review dates 
  • Address History which stores each participant’s historical residential addresses alongside valid-from/to date, tracking changes over time.  
  • Participant Provider Relationships linking NDIS participants to their service providers, capturing provider ID, relationship type (e.g., primary, plan manager), and start/finish dates. 
  • Plan Review Requests logging S48 reviews, also known as plan review requests, lodged when a participant’s circumstances change or they believe their funded supports are inadequate. It captures reason, lodgement-to-decision timeline, outcome, and linked plan identifiers for each request.  
  • Participant Outcomes holding participant survey responses, self-reported measures of independence, social participation, health and economic wellbeing, captured at plan reviews to track how NDIS supports are affecting each participant over time.  
  • Family Outcomes table storing caregivers’ survey responses, self-reported measures of family wellbeing, capacity to care, and community inclusion, collected at plan reviews to assess how NDIS supports impact participants’ families over time.
  • Outcomes Maps is a metadata reference table that catalogues all outcome-survey instruments used by the NDIS, including survey forms, question text, and allowable answer options. It contains no participant-level data and should be used to decode responses in Participants and Family Outcomes tables.  
  • Support Catalogue listing every NDIS support item, item number, description, unit of measure, location-specific price (inc. remote loadings), and validity dates, serving as the master price guide for plans and payments. 
  • Support Item recording every claimed support instance under a participant’s plan including item number, category, service date, delivered quantity, unit price and total claim amount. It enables granular analysis of utilisation and spend.
