When everyday life requires more than occasional help, the question of who qualifies for SIL can feel urgent. For participants, families and referrers, the answer is not based on a diagnosis alone. The NDIS considers whether a person needs ongoing, paid support to live as independently and safely as possible, particularly within a shared living arrangement.
Supported Independent Living, usually called SIL, can provide the regular assistance that makes a stable home life possible. It may include support with personal care, meals, household tasks, appointments, medication routines, building daily living skills and responding to changing needs. For people with complex disability, the right support can also provide continuity, safety and greater choice over how they live.
What is SIL and what does it fund?
SIL is funding for the disability-related support a participant needs at home. It is not funding for the house itself, rent, groceries, utility bills or everyday living expenses. It also differs from Specialist Disability Accommodation (SDA), which relates to the physical dwelling for eligible people with very high support needs or extreme functional impairment.
A participant may live in a shared home with other NDIS participants, in a home they rent or own, or in another suitable arrangement. In practice, SIL is most commonly used where support is needed across the day, overnight, or both, and where shared supports can be organised safely and appropriately.
The level of support is individual. Some people need help at planned times each day. Others require active overnight assistance, a responsive awake staff member, specialised communication approaches, behaviour support strategies, or workers trained in high-intensity care. SIL should reflect what the person genuinely needs, not force them into a roster that suits a provider.
Who qualifies for SIL under the NDIS?
There is no single SIL diagnosis list and no automatic approval. A person may be considered for SIL when they are an NDIS participant with a permanent and significant disability, and their functional support needs indicate that regular paid help in the home is reasonable and necessary.
The NDIS generally looks at whether the participant needs substantial assistance or supervision with daily activities. This could include showering and dressing, toileting, eating and drinking, preparing meals, moving safely around the home, managing health routines, communicating needs, maintaining a household, or taking part in the community.
SIL may be appropriate where support needs are ongoing and cannot reasonably be met by informal supports alone. For example, a parent may have been providing extensive care for years but is no longer able to safely sustain that role. A young adult may be ready to move from the family home but need consistent support to develop practical skills and avoid isolation. Another participant may be leaving hospital, an unsuitable placement or temporary accommodation and need a stable home-based support arrangement without unnecessary delay.
Complexity matters, but it is not limited to medical needs. A person may need SIL because of cognitive disability, psychosocial disability, autism, acquired brain injury, intellectual disability, physical disability or a combination of conditions. The key question is the impact on daily functioning and safety.
SIL is usually for significant, ongoing support needs
The NDIS often considers SIL where a participant requires support for much of the day, regular overnight support, or a high level of supervision. This does not mean everyone receiving SIL needs 24-hour one-to-one care. Shared support can be suitable when participants have compatible needs, preferences and routines, and when privacy and safety are protected.
For someone whose needs are limited to a few hours of help each week, other NDIS supports may be a better fit. Core Supports for daily personal activities, assistance with household tasks, community participation, support coordination, assistive technology or capacity-building therapies may provide what is needed without a SIL arrangement.
The evidence that helps a SIL request
A strong SIL request explains what happens in real life, rather than simply listing a condition. The NDIS needs clear evidence of the participant’s functional capacity, risks, goals and the support already available around them.
An occupational therapist’s functional capacity assessment is often central to this process. It can describe how the participant manages personal care, mobility, communication, domestic tasks, decision-making, sensory needs, emotional regulation and safety. It should also identify the consequences of support not being available, such as missed medication, poor nutrition, falls, vulnerability, distress, tenancy breakdown or loss of meaningful community access.
Other useful evidence may come from treating clinicians, psychologists, behaviour support practitioners, nurses, support workers, guardians, family members and current accommodation providers. Incident records, hospital discharge information and detailed support notes can be particularly relevant where needs are complex or have changed.
The most helpful evidence is specific. Rather than saying a person needs “support with meals”, it should explain whether they can plan meals, use appliances safely, recognise spoiled food, manage dietary requirements, respond to choking risks and clean up afterwards. It should also state how often assistance is needed and whether it requires prompting, direct help, supervision or a worker with particular skills.
Informal supports are considered, but families are not expected to do everything
The NDIS will consider support provided by family, friends and other unpaid carers. However, informal support must be reasonable and sustainable. It is not appropriate to assume that ageing parents, siblings, partners or friends can provide intensive care indefinitely, particularly where sleep disruption, manual handling, complex health needs or behaviours of concern are involved.
Being honest about what informal supports can and cannot safely provide is essential. This is not a judgement on a family’s commitment. It is a practical assessment of whether the current arrangement protects the participant’s wellbeing, dignity and future independence.
How the NDIS decides whether SIL is reasonable and necessary
As with other NDIS-funded supports, SIL must meet the reasonable and necessary criteria. The support should relate directly to the participant’s disability, assist them to pursue their goals, be likely to be effective and beneficial, represent value for money, and take account of support that could reasonably be provided through family, community or mainstream services.
The NDIS may also consider whether the proposed living arrangement is the least restrictive and most appropriate option. A good SIL proposal does not focus only on hours of staffing. It shows how support will build skills, uphold choice and reduce avoidable risk while allowing the participant to live an ordinary, meaningful life.
This can involve trade-offs. A highly individualised arrangement may offer more privacy but cost more than a shared home. Shared living can provide companionship and make round-the-clock support more viable, but it must be compatible with the participant’s communication style, routines, culture, sensory preferences and personal goals. The right answer depends on the person, not on a standard vacancy model.
SIL, SDA, STA and MTA are different supports
These terms are often used together, but they serve different purposes. SIL funds the staff support required in a home. SDA concerns the specialist features of a dwelling for a small group of eligible participants. A person can receive SIL without SDA, SDA without SIL, or both where their circumstances meet the criteria.
Short-Term Accommodation (STA) can provide a temporary change of environment, planned respite or support while skills are being developed. Medium-Term Accommodation (MTA) may assist when a participant is waiting for a confirmed long-term housing solution, including an SDA home. Neither automatically establishes eligibility for SIL, although time in temporary accommodation can help clarify a person’s ongoing support needs.
What to do if SIL may be suitable
Start by documenting daily support needs and the gaps in the current arrangement. Include what happens overnight, during health episodes, when routines change, and when unpaid carers are unavailable. Focus on the participant’s goals as well as risks: moving into their own home, strengthening daily living skills, maintaining relationships, participating in community life or having more control over their routine.
A support coordinator or allied health professional can help organise assessments, collect evidence and explore suitable home and support options. For urgent transitions, such as hospital discharge or a breakdown in current care, early communication and a clear risk picture are especially important. Providers with capability in complex care can assist in planning staffing, clinical oversight and safe continuity of support where the participant’s needs require it.
Funding decisions can change as circumstances change. If a participant’s health, functional capacity, informal supports or living situation has shifted, updated evidence may support a plan reassessment or review. A previous decision is not necessarily the final word.
SIL is not about taking independence away. At its best, it gives a person the dependable support needed to make more of their own choices, feel secure at home and build a life on their terms.
