NDIS vs State Disability Services: How the Transition Changed Provider Obligations

The Pre-NDIS Landscape

Before the NDIS, Australia's disability services were delivered through eight separate state and territory systems. Each jurisdiction had its own legislation, its own standards, its own funding model, and its own regulatory body. There was no national consistency.

How the old systems worked

Under the pre-NDIS model:

• Funding was block-granted — state governments received Commonwealth funding (through the National Disability Agreement) and distributed it to disability service organisations. Funding went to providers, not to individuals.
• Service allocation was rationed — because funding was limited and provider-based, individuals were placed on waiting lists for services. Some waited years for accommodation, respite, or therapy.
• Quality standards varied by state — Victoria had its own Human Services Standards, NSW had its own Disability Service Standards, Queensland had its own framework, and so on. There was no national consistency in what constituted quality service delivery.
• Regulation was fragmented — each state regulated its own providers under its own disability services legislation. Some states had robust compliance frameworks; others did not.
• Portability was minimal — a person who moved from Victoria to Queensland could lose their disability services entirely and have to reapply in the new state, potentially joining another waiting list.

State-by-state pre-NDIS systems

The lack of national consistency was a major driver behind the Productivity Commission's 2011 report recommending the creation of the NDIS. The report found that the existing system was "underfunded, unfair, fragmented, and inefficient" and that a national insurance approach was needed.

The Transition Timeline by State

The NDIS was not rolled out overnight. It was introduced progressively, starting with trial sites in 2013 and reaching full national rollout by mid-2020.

The NDIS Quality and Safeguards Commission followed a similar phased rollout, starting in NSW and South Australia on 1 July 2018 and reaching national coverage on 1 July 2020.

What Changed for Providers

The transition from state-based systems to the NDIS was the most significant structural change to disability services in Australian history. For providers, the changes were profound:

1. From block funding to individualised funding

Under state systems, providers received block grants to deliver services. They had guaranteed revenue and could plan staffing and operations around predictable funding. Under the NDIS, funding goes to individuals, and providers must compete for participants. Revenue is no longer guaranteed — it depends on attracting and retaining participants who choose your services.

2. From state regulation to national regulation

Instead of being regulated by their state department under state legislation, providers are now regulated by the NDIS Quality and Safeguards Commission under the NDIS Act 2013 and nationally consistent NDIS Practice Standards. This means one set of standards, one regulator, and one complaints process — regardless of which state you operate in.

3. From state standards to NDIS Practice Standards

Every state's quality standards were replaced by the NDIS Practice Standards for NDIS-funded services. Providers had to review and rebuild their entire policy and procedure suites to map to the new national standards. For many small providers, this was the most resource-intensive part of the transition.

4. From state worker checks to NDIS Worker Screening

State-based worker screening (police checks, Working with Children Checks, state-specific disability worker checks) was supplemented by the nationally consistent NDIS Worker Screening Check. While state-based checks still exist for non-NDIS purposes, NDIS-registered providers must ensure workers in risk-assessed roles hold an NDIS Worker Screening Check clearance.

5. From provider-led to participant-led

The NDIS fundamentally shifted the power dynamic from providers to participants. Under state systems, providers often determined what services a person received. Under the NDIS, participants choose their providers, direct their supports, and can change providers at will. This required a cultural shift for many organisations — from a welfare model to a consumer-directed model.

Residual State Services That Still Exist

Despite the NDIS being a national scheme, state and territory governments retain responsibility for a range of services that intersect with disability but are not funded by the NDIS:

• Public health services — hospital care, emergency departments, community mental health services, public dental care
• Public housing — social housing, homelessness services, crisis accommodation (distinct from SDA, which is NDIS-funded)
• Education — school-based disability support (in-class aides, specialist schools, learning support) is a state responsibility, though the NDIS may fund some therapeutic supports delivered in schools
• Justice — disability support within the criminal justice system (courts, corrections, forensic disability services) is primarily a state responsibility
• Child protection — child protection services for children with disability remain with state child protection departments
• Transport — public transport accessibility, taxi subsidy schemes, and community transport are state-funded (the NDIS may fund transport assistance for individual participants in some circumstances)
• Advocacy — some state-funded disability advocacy services continue alongside NDIS-funded advocacy

For providers, this means you may have participants who receive services from both the NDIS and state systems simultaneously. For example, an NDIS participant living in a SIL house may also access state-funded community mental health services, attend a state-funded specialist school, or have involvement with the state justice system.

The APTOS Framework

The Applied Principles and Tables of Support (APTOS) is the framework that defines which system is responsible for which services. Agreed between the Commonwealth and state/territory governments, the APTOS prevents duplication and clarifies boundaries.

Key principles

• The NDIS is the funder of last resort — the NDIS will not fund supports that are the responsibility of another system (health, education, justice, housing)
• Mainstream services are responsible for making reasonable adjustments — schools, hospitals, and other mainstream services must make their services accessible to people with disability, at their own cost
• The NDIS funds reasonable and necessary disability-specific supports — supports that are directly related to a person's disability and are not the responsibility of another system

Common boundary disputes

Despite the APTOS, disputes about which system is responsible for a particular support are common. The most frequent boundary issues include:

• Health vs NDIS — where does acute health care end and NDIS-funded disability support begin? For example, post-surgery rehabilitation may start as a health responsibility and transition to NDIS-funded support.
• Education vs NDIS — who funds a specialist aide in the classroom? Generally, the school funds in-class support, but the NDIS may fund individual therapy (e.g., speech pathology) that is delivered at school.
• Housing vs NDIS — the NDIS funds SDA (Specialist Disability Accommodation) for eligible participants, but public housing for people with disability who do not qualify for SDA remains a state responsibility.
• Justice vs NDIS — the NDIS may fund supports for a participant who is in the justice system (e.g., support coordination while on bail), but the actual justice system services (courts, corrections, forensic disability) are state-funded.

Providers navigating these boundary issues should document clearly which funder is responsible for which support and escalate unresolved disputes through the participant's support coordinator or the NDIA.

Key Interface Areas

Health interface

The health-NDIS interface is the most commonly contested boundary. Key principles:

• Acute and emergency health care is always a state health responsibility
• Ongoing health-related supports for disability management (e.g., nursing care in a SIL house for a non-acute, ongoing condition) may be NDIS-funded
• Mental health treatment is generally a state health responsibility, but the NDIS funds psychosocial disability supports (recovery coaching, community participation)
• Allied health therapy can be NDIS-funded if it relates to the participant's disability and is included in their plan

Housing interface

The NDIS funds two types of housing support:

• Supported Independent Living (SIL) — the support component (workers who assist the participant in their home)
• Specialist Disability Accommodation (SDA) — the bricks-and-mortar accommodation for participants with extreme functional impairment or very high support needs

Mainstream public housing, crisis accommodation, and homelessness services remain state responsibilities. A participant who is homeless but not eligible for SDA would access state housing services, while their NDIS plan might fund support coordination to help them navigate the housing system.

Justice interface

Participants involved in the justice system present unique challenges. The NDIS recognises that disability supports should continue even when a participant is in custody or under supervision, but the justice system itself is a state responsibility. Common scenarios include:

• An NDIS participant on a Community Treatment Order — NDIS funds their disability supports; the state health system funds the mental health treatment
• An NDIS participant in custody — NDIS plan is generally suspended while in custody, but may resume upon release
• An NDIS participant in a forensic disability facility — complex interface between state forensic services and NDIS-funded supports

Impact on Small Providers

The transition from state systems to the NDIS has had a disproportionate impact on small providers. Here is what small providers have experienced:

Positive impacts

• Market access — small providers can now serve participants across the country without being tied to state government contracts
• Participant choice — the NDIS's emphasis on participant choice means small providers who deliver high-quality, personalised services can compete effectively against larger organisations
• National consistency — one set of standards to comply with, rather than navigating multiple state frameworks

Challenging impacts

• Revenue uncertainty — the loss of block funding meant many providers lost predictable revenue and had to learn how to operate in a competitive market
• Compliance burden — the NDIS Practice Standards and audit requirements are more demanding than some state-based frameworks, particularly for small providers with limited administrative resources
• Documentation demands — the NDIS requires extensive documentation (progress notes, service agreements, incident reports, complaints records) that some state systems did not require at the same level of detail
• Cash flow — claiming against individual participant plans creates cash flow variability, particularly when plans are under review or when participants change providers

For small providers navigating these challenges, efficient documentation systems are essential. Our free NDIS Notes Rewriter helps support workers write compliant progress notes quickly, and the SIL Rescue Kit provides all the policies and procedures you need for audit readiness.

Looking Forward: The Continuing Evolution

The relationship between the NDIS and state systems continues to evolve. Key developments to watch:

• NDIS reforms (2024-2027) — the NDIS Review recommendations are being progressively implemented, including changes to the registration framework, pricing, and the interface with other systems
• Foundational supports — the concept of "foundational supports" (lower-level supports available outside an individual NDIS plan) is being developed, which may involve state governments co-funding some disability services
• Interface agreements — the APTOS is being reviewed and updated to address ongoing boundary disputes, particularly in health, housing, and justice
• State disability strategies — most states maintain their own disability inclusion strategies and action plans, which sit alongside the NDIS and address broader disability policy goals

For providers, the key message is: the NDIS is not the entire disability service system. It is a critical component, but it operates alongside state systems that continue to fund and deliver services. Understanding where one system ends and the other begins is essential for delivering quality, compliant supports.
