What Is Supported Independent Living? SIL Explained

What this handbook is for

Supported Independent Living is one of the largest single line items in the NDIS and one of the least well explained. Families arrive at it in a hurry, usually because something has changed at home, and they get handed a term that sounds self-explanatory and is not.

This is part one of four. It covers what SIL actually is, what it is not, and how the pieces of a supported home fit together. Part two covers eligibility and the evidence that decides it. Part three covers finding and touring homes. Part four covers the first ninety days after someone moves in.

We run supported homes ourselves, so treat this as a practitioner's account rather than a neutral one. Where something is our judgement rather than a rule, we say so.

The definition, stripped back

SIL is funding for the support workers who help an adult participant with the ordinary business of living in their own home. Personal care, cooking, cleaning alongside you, prompting medication, getting out the door in the morning, being there overnight where the evidence supports it. It sits in the Core part of an NDIS plan, and the NDIA describes it in the home and living section of the NDIS Operational Guidelines.

The critical word in the name is not independent, it is supported. SIL exists for people who need help with daily tasks at home most days, often around the clock, and the point of it is not to remove that help but to organise it well enough that a person can still run their own life inside it.

The second critical thing is what SIL does not pay for. It pays for people. Not the house, not the rent, not the groceries, not the electricity. That boundary is the source of nearly every misunderstanding families have about this support, and it is worth saying twice.

Four things SIL is not

SIL is not a building. There is no such thing as a SIL house in the way there is such a thing as a hospital. SIL is a funding arrangement that follows a person. If you move, it moves with you. Providers advertise homes as SIL homes because that is the shorthand everyone uses, but what they mean is a house with a funded support arrangement running in it.

SIL is not automatically a group home. Most SIL is delivered in shared houses of two to five people, because sharing support is what makes the arrangement affordable and because plenty of people prefer company. It can also be delivered to someone living alone. Shared is the norm, not the definition.

SIL is not automatically 24 hour support. Some homes have staff awake all night, some have staff asleep in the house, some have nobody overnight at all. What you get depends on the assessed needs of the people who live there, not on the label. Ask the direct question about any specific home, because the answer varies house by house.

SIL is not a number of hours you can look up. There is no table of SIL hours by disability type. Support is worked out through a roster of care built around a real week, then priced. Two people with the same diagnosis can be funded very differently and both be correct. We go through how that roster is built in how many hours of support you get in SIL.

Who it is designed for

SIL is for adult participants whose daily living needs are substantial and ongoing. In practice that tends to mean people who need help with personal care or medication most days, people who cannot safely be alone for long stretches, and people whose nights need someone present.

It is often the answer when the informal support at home has reached its limit. A common version of this is a parent in their seventies still doing overnight care for an adult child in their forties, where everyone can see the arrangement has perhaps three years left in it. Starting that conversation early rather than after a hospital admission is the single most useful thing a family in that position can do.

It is not the only answer, and part of using this handbook well is knowing when to stop reading it. If someone wants to live alone, or with one person of their choosing, an Individualised Living Option may fit better. If the need is short term while something else is arranged, medium or short term accommodation may be the right tool. Our comparison of the full set of NDIS housing options maps out where each one sits.

The five moving parts of a supported home

Once you see a supported home as five separate things rather than one, most of the confusion clears up.

The house. Bricks and mortar, owned by someone. Possibly the support provider, possibly a separate housing provider, possibly a private landlord, occasionally a family.

The tenancy. Your legal right to live there. This is a housing document, not a disability document, and it should ideally be separate from your support agreement so that a problem with one does not threaten the other.

The roster of care. The week-long map of who needs support, when, and how many workers are on. Your provider proposes it, the NDIA assesses and prices it, and it is the closest thing you have to a written description of your actual day.

Your plan. The funding. Yours alone, held by you, and portable. Each resident in a shared house has their own.

The household. The people. The part that no document controls and the part that decides whether someone is happy. It is also the part providers talk about least in a first meeting, which is why the visit matters so much more than the brochure.

The three payments that can sit on one house

This is where most families get lost, so here it is in one place. A single supported home can have three different streams of money running through it, going to three different places.

The SIL payment goes from the NDIA to the support provider, for staffing. If the house is also enrolled Specialist Disability Accommodation, a second and separate SDA payment goes from the NDIA to the housing provider, for the building itself. And the third stream is your own money, from the Disability Support Pension and any Commonwealth Rent Assistance you receive, covering rent or board, food, power and everything personal.

Notice that you only handle the third one. The other two are paid over your head, which is exactly why the service agreement needs to show the support side and the personal side on separate lines. We set out that split in detail in who pays for what in SIL.

How it gets into a plan, in outline

SIL is not requested with a form and granted. It is built from evidence that a person needs substantial help with daily living at home, and from a proposed roster of care that shows what that help looks like across a week. Occupational therapy reports, functional assessments, night records, incident histories and a clear statement of what has already been tried all feed into it.

Funding decisions sit with the NDIA and turn on the strength of that evidence, so nobody, including us, can tell you that a request will succeed. What can be said is that the requests that go badly are almost always the ones where the daily reality was described in general terms rather than specific ones. Part two of this handbook is entirely about that evidence, because it is where the outcome is actually decided.

If you are further along and comparing real houses, our current vacancies list what each home offers, and part three covers what to look for once you are standing in one.

Part two: eligibility and the evidence that matters. What the NDIA is actually assessing, which documents carry weight, how to describe a night honestly, and the specific ways strong cases get written weakly.

If you cannot wait for it, the short version is this. Write down what happens in a bad week rather than an average one, get the professionals who know the person to describe function rather than diagnosis, and keep a record of the nights. Everything else in part two is detail on those three sentences.
