Grounding Summary

Informal supports refer to unpaid assistance provided by a participant's family, friends, and social networks. Mainstream supports encompass other government and community service systems outside the NDIS, such as health, education, and justice services. These concepts establish the boundaries of NDIS funding responsibilities. Support coordinators must rigorously document the limits, exhaustion (such as carer burnout), or unavailability of these non-NDIS supports to legally justify why targeted NDIS intervention is reasonable and necessary for the participant.

Detail

Informal Supports Defined

Informal supports are the unpaid, non-contractual assistance that participants receive from their personal networks:

Family members: Parents, spouses, siblings, children providing care and assistance
Friends: Personal relationships that provide practical or emotional support
Social networks: Community groups, religious organisations, voluntary associations
Neighbours: Informal assistance from local community members

These supports are typically unpaid and based on personal relationships rather than formal service arrangements.

Mainstream Supports Defined

Mainstream supports are services provided by general government systems and community organisations:

Health system: Medicare, public hospitals, community health services, mental health services
Education system: Schools, universities, vocational training supports
Justice system: Probation services, community corrections, victim support
Housing services: Public housing, community housing providers
Income support: Centrelink, pensions, disability support pension

The NDIS is not intended to duplicate services that should be provided by these general systems.

The Legal Boundary

Section 34(1)(e) of the NDIS Act requires the NDIA to consider "what it is reasonable to expect families, carers, informal networks and the community to provide" before approving funded supports. Section 34(1)(f) specifies that a support can only be funded if it is "not more appropriately funded or provided through other general systems of service delivery."

These provisions create a legal boundary: the NDIS must only fund supports that cannot reasonably be provided by informal networks or mainstream systems.

What It Means for Practitioners

Support coordinators must document:

What informal supports exist: Who provides assistance, what tasks they handle, how many hours per week
Where informal supports are exhausted: Carer burnout, physical limitations, conflicting work/family demands
What mainstream supports are available: Which services the participant accesses, gaps in coverage
Why NDIS intervention is necessary: The specific gap that only NDIS funding can fill

This documentation belongs in Block 1 (Environmental and Personal Context) of the Participant Statement toolkit. Establishing the limits of informal and mainstream supports creates the baseline evidence needed to justify budget architecture recommendations and funding requests.

Evidencing Exhaustion in Practice

RS-07 research establishes a critical distinction: it is insufficient to simply list who provides informal support. Documentation must explicitly state the limits of that support to prove exhaustion. This means:

For informal supports: Identify exact tasks performed, hours involved, and specific sustainability risks — such as aging carers, carer health limitations, competing work commitments, or the inappropriateness of certain support tasks within a personal relationship.
For mainstream supports: Explicitly state where these systems' responsibilities end. For example, a GP manages general health but cannot provide the intensive, disability-specific occupational therapy required for executive functioning barriers — which falls outside standard Medicare provisions.

A practitioner who merely states "the participant has family support" without documenting its limits leaves the NDIA free to assume those supports can absorb the participant's needs. Crucially, the risk profile built from this exhaustion documentation directly anchors subsequent PACE budget architecture recommendations — such as shorter funding periods or digital locks on vulnerable supports.

The Exhaustion Principle

Not all informal support exhaustion means carer burnout. Valid reasons include:

Carer has competing work or family commitments
Carer has their own health limitations
The support required is beyond the carer's capacity or expertise
Geographic distance limits available support
The relationship dynamic makes certain supports inappropriate

Practitioners must document these limitations specifically and realistically to satisfy the reasonable and necessary criteria.

Legislative Basis

Reference	Provision	Relevance to this article
NDIS Act 2013 s33(1)(b)(ii)	Participant statement content	Mandates inclusion of informal and community supports within the environmental and personal context
NDIS Act 2013 s34(1)(e)	Reasonable and necessary — informal supports	Requires NDIA to consider what is reasonable to expect from families, carers, and informal networks
NDIS Act 2013 s34(1)(f)	Reasonable and necessary — mainstream supports	Specifies that NDIS only funds supports not appropriately provided through general service systems
