The requirement for NDIS service agreements flows from two primary legislative sources:

Section 106 of the NDIS Act 2013 establishes the framework for service delivery by registered providers and the requirement to comply with the NDIS (Registered Providers of Supports) Rules. The NDIS (Registered Providers of Supports) Rules 2013 — specifically Part 3, Division 3.3 — set out the requirements for service agreements, including what must be included and how agreements must be entered into.

The NDIS Commission's guidance document "NDIS Service Agreements — A Guide for Participants and Providers" provides additional practical detail and is the primary reference for what the Commission considers to be an adequate service agreement. While this guidance does not have the force of law, auditors use it as the benchmark when assessing service agreements during certification and surveillance audits.

A service agreement is a contract between the provider and the participant (or their nominee). It must be negotiated in a way that is accessible to the participant, provided in plain English, and executed voluntarily. Service agreements that are presented on a take-it-or-leave-it basis, that are signed without adequate explanation, or that contain terms the participant does not understand, may be challenged through the NDIS Commission's complaints process.

Key principle

Under Core Module Outcome 1.4 (Autonomy and Independence), participants have the right to negotiate the terms of their service agreement. A provider who presents a non-negotiable, standard agreement without discussing the terms with the participant is not meeting this standard. Service agreements must be genuinely person-centred documents.

The 12 Essential Elements of an NDIS Service Agreement

Drawing on the NDIS Commission's guidance and the requirements of the NDIS (Registered Providers of Supports) Rules 2013, every NDIS service agreement should include the following 12 elements:

Element 1
Parties to the Agreement
Full legal name of the registered provider, the participant's full name and NDIS number, and (where applicable) the name and relationship of any nominee, guardian, or authorised representative acting on the participant's behalf. The agreement must clearly identify who is bound by its terms.
Element 2
Supports to Be Delivered
A specific description of the supports the provider will deliver. This should align with the participant's current NDIS plan and reference the relevant support category and line items where possible. Vague descriptions such as "daily living supports" without further detail are insufficient. The description should be specific enough that both parties understand exactly what will be delivered.
Element 3
How and When Supports Will Be Delivered
The schedule of supports — including frequency, hours per week or fortnight, times of day, and location. For SIL participants, this includes the address of the SIL property and the schedule of overnight and waking support hours. Changes to the scheduled support delivery should be managed through a variation process documented in the agreement.
Element 4
Fees and NDIS Plan Budget
The price for each support item, expressed in a way that is transparent and consistent with the current NDIS Pricing Arrangements and Price Limits. The agreement must state the hourly or unit rate, the support category, and the NDIS line item code. Any fees charged above NDIS rates (e.g., for services funded outside of NDIS) must be separately itemised. The agreement must not claim or commit NDIS funds beyond the participant's current plan budget.
Element 5
Invoicing and Payment Arrangements
How the provider will claim NDIS funds — including whether they will claim from NDIA directly (agency-managed), via a plan manager (plan-managed), or be invoiced by the participant (self-managed). Payment timeframes, invoice formats, and the process for disputing an invoice should be included. The agreement should specify the payment model that applies to this specific participant.
Element 6
Participant Responsibilities
What the participant agrees to do — for example, providing reasonable notice of cancellations, advising the provider of changes to their NDIS plan, providing a safe environment for workers (relevant for in-home supports), and communicating concerns in a timely manner. These obligations must be reasonable and not so burdensome as to restrict participant rights.
Element 7
Provider Responsibilities
The provider's obligations under the agreement and the NDIS framework — including delivering supports as agreed, employing and screening workers appropriately, maintaining confidentiality, complying with the NDIS Code of Conduct, respecting participant privacy and dignity, and responding to complaints and feedback. This section should reference the provider's relevant policies.
Element 8
Cancellation and Short Notice Cancellation Policy
Clear terms for cancellation by either party, including the notice period required, when short notice cancellation fees apply, and the applicable rate (consistent with current NDIS Pricing Arrangements). The agreement must clearly distinguish between planned cancellation (participant gives adequate notice) and short notice cancellation (participant cancels within the short notice window, currently 7 days for most supports).
Element 9
Varying and Ending the Agreement
The process for varying the agreement (e.g., when the participant's NDIS plan is reviewed, or when support needs change), and the process for ending the agreement. Both parties should be able to end the agreement with reasonable notice. The notice period for provider-initiated termination must be sufficient to allow the participant to find alternative supports — a standard period is 28 days for SIL and other high-frequency supports.
Element 10
Feedback, Complaints, and Dispute Resolution
How the participant can provide feedback or make a complaint, including both the provider's internal complaints process and the participant's right to contact the NDIS Commission directly. The agreement must not contain terms that discourage or prevent participants from making complaints or accessing external review. Contact details for the NDIS Commission (1800 035 544) should be included.
Element 11
Participant Rights and Confidentiality
An explicit statement of the participant's rights under the NDIS Code of Conduct — including the right to be treated with dignity and respect, to make decisions about their own life, to have privacy protected, and to access supports without discrimination. Reference to the Privacy Act 1988 and how the provider will handle personal information. This is sometimes included as a separate Participant Rights Statement (Document 28 in the SIL Rescue Kit) attached to the agreement.
Element 12
Signatures and Date
Signed and dated by both the provider (authorised representative) and the participant (or nominee). Both parties must receive a copy of the signed agreement. For participants with complex communication needs, the agreement must be accessible — this may require Easy Read versions, supported decision-making processes, or involvement of an advocate.

SIL-Specific Requirements

Service agreements for Supported Independent Living supports have additional requirements and complexities that go beyond the standard framework.

Separating Housing and Support

This is the most critical SIL-specific requirement. If the provider also owns or manages the SIL property, the service agreement for support delivery must be completely separate from any tenancy agreement. The NDIS Commission's position is clear: a participant's access to housing must not be contingent on receiving support services from the same provider, and a participant must be able to change their support provider without losing their home.

The support service agreement should contain no provisions about tenancy, rent, or housing obligations. These must be in a separate tenancy agreement governed by applicable state or territory residential tenancy legislation.

Hours and Rostering

A SIL service agreement must clearly state the agreed support hours — including active support hours, sleepover hours, and any on-call arrangements. Many disputes in SIL arise from ambiguity about what "support" means during overnight periods. Be specific: does the overnight shift include sleepover support (worker asleep on-site, awoken if needed) or active nighttime support (worker awake throughout)?

Participant Contributions

Where a SIL participant contributes to their own living costs (rent, food, utilities) from their Disability Support Pension or other income, the service agreement should not commingle these personal contributions with NDIS-funded supports. The agreement should clearly delineate what is NDIS-funded versus what the participant pays from their own income.

House Rules and Shared Living

For shared SIL houses, providers sometimes develop house rules governing shared spaces, noise, visitors, and communal living expectations. These rules must not be incorporated into the service agreement in a way that restricts participant rights — particularly the right to have visitors, to use their own home as they choose, and to make decisions about their living environment. House rules, if they exist, should be a separate document and should be developed collaboratively with all residents.

Participant Rights in Service Agreements

Under the NDIS Act 2013 and the NDIS Code of Conduct (established under the NDIS (Code of Conduct) Rules 2018), participants have rights that cannot be contracted away in a service agreement. Clauses that limit or remove these rights are unenforceable and may constitute a Code of Conduct breach. These include:

Cancellation and Notice Period Requirements

Cancellation terms are one of the most contested areas of NDIS service agreements. The NDIS Pricing Arrangements and Price Limits (updated annually by the NDIA) set the framework for cancellation fees that providers may charge.

Under the current Pricing Arrangements, providers may charge a cancellation fee where:

For SIL supports, which are ongoing and rostered rather than episodic, the cancellation framework operates differently. SIL supports are typically charged based on agreed rostered hours rather than individual bookings. The service agreement should clarify how planned absences (e.g., participant in hospital) are handled from a billing perspective, consistent with the NDIS Pricing Arrangements guidance for SIL.

How to Avoid Common Service Agreement Disputes

1. Scope creep disputes

Problem: The participant expects supports that are not clearly described in the agreement. A participant who believes the service agreement covers "all daily living support" may expect shopping, transport to appointments, and social activities — but the provider only intended to cover personal care and meal preparation.

Solution: Be exhaustively specific in the "Supports to Be Delivered" section. List every support type, the frequency, and what is explicitly not included. If the scope might change over time, include a variation process.

2. Fee disputes

Problem: Participants receive invoices that are higher than expected, or are charged for supports they did not receive.

Solution: Include the specific NDIS line item codes and hourly rates in the agreement. Provide participants with itemised invoices. Implement a process for participants to query invoices before payment is processed.

3. Exit disputes

Problem: A participant wants to change providers but the service agreement makes exit difficult, costly, or unclear.

Solution: Include a clear, simple exit clause with a reasonable notice period. For SIL supports, 28 days is standard. Never include financial penalties for early termination that would not exist under standard contract law.

4. Unsigned or unsigned copies not provided

Problem: During an audit, the provider cannot produce a signed service agreement for a participant.

Solution: Implement a document control process that ensures service agreements are signed before supports commence, copies are provided to participants, and signed copies are stored in the participant's file. Service agreement status should be tracked in your Document Control Register (Document 48 in the SIL Rescue Kit).
