NDIS Overhaul: Australia's $70 Billion Disability Scheme Faces Its Biggest Reform

The government aims to slash annual NDIS spending growth from over 10% to just 2% by 2030, cutting participant numbers from 760,000 to 600,000 and saving up to $38 billion over four years.

The Financial Reality

The National Disability Insurance Scheme (NDIS) is now the federal government's second-fastest growing budget expense—and the numbers are staggering.

Current trajectory: Without changes, the scheme was forecast to exceed $63 billion by 2028-29 and reach $70 billion by 2030. This year alone, it will cost $52 billion.

Growth rates are accelerating: The annual growth rate hit 10.3% in the last financial year and climbed to 11.3% in the March 2026 quarter—adding 13,000 new participants in just three months.

The Productivity Commission's 2011 report originally estimated the scheme would support 410,000 participants at a cost of $13.5 billion annually.

The Government's Target

The objective is stark: reduce annual growth to an average of 2% over the next four years—below the current inflation rate—before returning to 5% from 2030.

Key Reform Measures

Tighter Eligibility: Diagnosis No Longer Guarantees Access

The current system grants automatic access to people with specific diagnosed conditions, including Autism Spectrum Disorders Level 2 and 3. These "access lists" will be scrapped.

New criteria by January 2028: Access will be based on "a significant reduction in a person's functional capacity that impacts their day-to-day living," according to Health Minister Mark Butler.

A "permanence test" will require individuals to exhaust "all appropriate" treatment options before accessing the scheme. The definition is clear:

• All appropriate treatment must be undertaken
• No other treatment is likely to materially improve the impairment
• The impairment must be likely lifelong

Existing participants will be reassessed as their plans come up for renewal.

Projected Participant Numbers: 760,000 to 600,000

The government projects the changes will reduce participants from approximately 760,000 to about 600,000 by 2030.

Treasury modelling shows: 241,000 people will exit the scheme over four years, with an additional 110,000 diverted from entry. Without changes, numbers were projected to reach 900,000 to 940,000 by 2030-31.

The first 33,000 existing participants are expected to be transitioned off the scheme by June 30, 2028, growing to 125,000 by mid-2029.

Expanded Provider Registration

Currently, approximately 94% of NDIS providers (nearly 260,000) are unregistered. Unregistered providers can deliver services to 26% of participants who self-manage and 68% whose plans are managed by a third party.

Under reform: Registration will expand to include higher-risk activities, personal care, daily living supports, and supports in closed settings. 90% of payments would go to registered providers under a tiered, risk-based model.

New Ministerial Powers—And Controversy

The proposed legislation grants the NDIS minister unprecedented authority to:

• Reduce social and community participation budgets by up to 50%
• Cut capacity building budgets by up to 10%
• Cap support hours, participant-to-worker ratios, and total funding for specific supports

Crucially, these decisions would not be subject to merits review.

The government aims to reduce the average participant plan spend from approximately $31,000 to about $26,000 and scale back social and community participation supports—which have tripled in five years.

Anti-Fraud Measures

The NDIA estimates 8.3% of payments ($3.7 billion out of $45 billion) were lost to "integrity leakage," including fraud and inadvertent non-compliance. The Australian Criminal Intelligence Commission has reported organized crime groups using the NDIS for money laundering.

Proposed measures include:

• Civil penalties for claiming services not provided
• Extended record-keeping (up to 7 years for providers, 3 years for participants)
• Treating unsubstantiated claims as debts
• Entry, search, and seizure powers for investigations
• Reducing claim submission time from 2 years to 90 days
• A digital payments scheme for oversight

Minister Butler stated fraud is "not a huge part of the growth in the scheme" but that integrity measures are necessary. The NDIS Fraud Fusion Taskforce has led to 25 successful prosecutions and over 600 active investigations, with more than 2,500 providers removed.

Stakeholder and Political Reactions

State Governments: "Extraordinary" Opposition

State and territory disability ministers submitted a joint criticism of the reform bill to a Senate inquiry, warning the changes exceed prior review recommendations and are inconsistent with earlier national cabinet commitments.

"The rapid pace of reform, focused on expenditure constraint, risks people with disability being placed in inappropriate settings like hospitals or receiving no services." — State and territory disability ministers

Treasurer Jim Chalmers warned state leaders they would be nearly $3 billion worse off over two years if they do not transition to a new disability support system. Health Minister Mark Butler described the state submission as "extraordinary," noting states had agreed to a plan to reduce spending and accepted a $25 billion increase in federal hospital funding.

Political Divide

• Coalition: Shadow NDIS Minister Melissa McIntosh called the announcement a "complete bombshell" and confirmed "zero consultation with the Coalition." In-principle support for "sensible reforms" but concerns about lack of detail.

• Greens: Disability spokesperson Jordon Steele-John described the changes as "cynical and cruel" and "one of the most dangerous pieces of legislation" for disabled people.

• Crossbench: Independent MPs led by Monique Ryan expressed concerns about prioritizing budget savings over support for vulnerable individuals.

Disability Advocacy Groups

People with Disability Australia (PWDA): Acting CEO Megan Spindler-Smith warned that restrictive practices could harm disabled people and that the government has not provided evidence of the fraud it cites.

Children and Young People with Disability Australia (CYDA): CEO Skye Kakoschke-Moore testified the bill "represents some very dangerous changes that would impact the lives of people with disability."

Women With Disabilities Australia: CEO Sophie Cusworth identified risks including loss of essential supports, shifting costs onto families (particularly women), and potential gender bias.

Australian Human Rights Commission: Disability Discrimination Commissioner Rosemary Kayess warned the legislation could leave people in "unsafe situations" and compromise rights. The commission described a two-week consultation period as "wholly inadequate."

NDIS Reform Advisory Committee (RAC): The committee stated the bill would cause "material harm" to participants and concentrate power in the health minister.

The Senate inquiry received over 4,000 written submissions, with many expressing concerns about access, safety, and the risk of inappropriate placements or loss of services.

Related Programs

Thriving Kids Program

The federal government and states have agreed to allocate $4 billion for children with autism and developmental delays who have mild to moderate support needs. The program will be co-run by states and territories, with costs split equally (50/50).

Timeline: Rollout begins October 2026, fully operational by January 2028—when NDIS eligibility criteria change. Victoria has announced its version; Queensland has not yet signed on.

Foundational Supports

The government has allocated $3 billion over five years for programs outside the NDIS for those no longer eligible, to be matched by states and territories. The Productivity Commission has identified approximately 500,000 Australians with moderate to severe psychosocial illness who do not receive support through the NDIS or other government-funded programs.

Legislation and Implementation Timeline

The National Disability Insurance Scheme Amendment (Securing the NDIS for Future Generations) Bill was introduced on May 14, 2026.

The bill has been referred to a Senate inquiry, with the government seeking passage before the parliamentary winter break in July.

Research and Data Context

Autism and NDIS Participation

Public policy economist Robert Breunig from ANU co-authored research suggesting a 32% increase in reported autism prevalence following the NDIS's introduction. The study indicated government-subsidized healthcare providers became less likely to provide diagnoses, while disability service providers became more likely to do so.

Autism is the primary diagnosis for 43% of current NDIS participants (324,200 participants). People with autism are nearly four in five of all new entrants—with participation increasing by 24% in one year and 14% the prior year.

Public Opinion

A survey by Talbot Mills Research found that only 42% of Australians think the NDIS offers value for money, compared to 79% who see Medicare as good or very good value. Sixty-one percent agreed the scheme is broken and costing too much.

An ANU survey in March 2024 found life satisfaction levels lower than during COVID-19 lockdowns, with financial stress and job market anxiety cited as contributing factors.

Regulatory and Advisory Delays

The NDIS Reform Advisory Committee (RAC) recommended delaying the rollout of a new support planning system using the Instrument for the Classification and Assessment of Support Needs (I-CAN) . The committee advised implementation should not begin before October 1, 2024—rather than the scheduled July 1 start—to "allow sufficient time for development, testing and meaningful public consultation."

The I-CAN tool aims to standardize planning by having participants interviewed by an assessor, with findings processed by an algorithm to generate a proposed budget—referred to as "robo-planning" by some in the disability community. NDIS Minister Jenny McAllister stated in December 2023 that the "rules and policy arrangements to support the new process" were still being developed.
