Understanding the cost of Supported Independent Living (SIL) can feel confusing for many NDIS participants and families. One of the biggest misconceptions is that SIL is “rent assistance” or that the NDIS pays for everything related to housing. In reality, SIL funding is specifically designed to cover support services that help participants live more independently.
This guide explains what SIL costs actually include, what the NDIS funds, what participants usually pay themselves, and how SIL budgets are calculated. Whether you are exploring SIL for yourself or supporting a family member, this article will help you understand the financial side of Supported Independent Living more clearly.
According to the official NDIS website, SIL funding supports people who require regular assistance at home, often with support available 24 hours a day, 7 days a week.
What is Supported Independent Living (SIL)?
Supported Independent Living, commonly called SIL, is an NDIS-funded support designed for participants who need help with daily living activities while living independently.
SIL can include support with:
- Personal care and hygiene
- Meal preparation
- Cleaning and household tasks
- Medication management
- Building life skills
- Community participation
- Overnight supervision
- Safety and behavioural supports
SIL funding focuses on the support workers and care services, not the physical home itself.
Does the NDIS Pay for SIL Accommodation?
This is one of the most common questions families ask.
The answer is no. SIL funding does not usually pay for:
- Rent
- Groceries
- Utility bills
- Internet
- Household items
- Daily living expenses
Participants are generally responsible for normal living costs, just like anyone else living independently.
If a participant requires specially designed housing because of a significant functional impairment, they may also qualify for Specialist Disability Accommodation (SDA). SDA covers the housing component, while SIL covers the support services inside the home.
What Does SIL Funding Actually Cover?
SIL funding is designed to pay for support workers who assist participants with daily living and independence goals.
Funding may include:
Daily Living Assistance
Support workers can assist with:
- Showering and dressing
- Cooking meals
- Cleaning
- Laundry
- Medication reminders
Skill Development
SIL also focuses on helping participants build independence skills such as:
- Budgeting
- Meal planning
- Communication skills
- Social participation
- Household routines
Overnight and 24/7 Support
Some participants require:
- Active overnight support
- Sleepover support
- Continuous supervision
- Complex behavioural support
The level of support directly impacts overall SIL funding costs.
How Much Does SIL Cost?
There is no fixed SIL price.
The cost of SIL depends on several factors, including:
| Factor | Impact on Cost |
| Level of support needed | Higher support needs increase funding |
| Shared or individual living | Shared supports may reduce overall costs |
| Overnight support requirements | 24/7 care increases funding |
| Behavioural or medical complexity | Complex care requires higher funding |
| Number of support workers required | More staff means higher support costs |
| Location and provider model | Costs may vary by provider and region |
Because every participant has different support needs, SIL funding is individually assessed by the NDIA.
Average SIL Funding Levels
Although funding varies significantly, SIL is considered one of the higher-cost NDIS supports because it often involves ongoing daily care.
Typical SIL funding may range from:
| Support Level | Approximate Annual Funding |
| Lower support needs | $50,000 – $120,000 |
| Moderate support needs | $120,000 – $250,000 |
| High or complex support needs | $250,000+ |
These figures are only general estimates. Actual SIL budgets depend on assessments, support ratios, and the participant’s goals.
The NDIS uses detailed support assessments and roster-of-care calculations to determine reasonable and necessary funding.
What is a Roster of Care?
A roster of care is a detailed support schedule used to calculate SIL funding.
It outlines:
- The participant’s daily support needs
- Staffing ratios
- Overnight supports
- Shared supports
- Active care hours
- Supervision requirements
For example:
- A participant needing occasional prompting may require lower funding
- A participant needing 1:1 active overnight support may require significantly higher funding
This roster helps the NDIA determine the appropriate SIL budget.
Does Shared SIL Reduce Costs?
In many SIL homes, support workers assist multiple participants living together.
For example:
- 1 support worker may support 2 or 3 residents
- Shared support arrangements can reduce individual funding requirements
- Shared living may also improve social connections and independence
However, participants with higher needs may still require individualised support within shared settings.
Additional Costs Participants Should Expect
Even with SIL funding, participants may still contribute to:
| Personal Expense | Usually Paid By Participant |
| Rent | Yes |
| Groceries | Yes |
| Utilities | Yes |
| Internet | Yes |
| Entertainment | Yes |
| Personal items | Yes |
Families should plan for these ongoing living expenses separately from SIL funding.
How Do You Apply for SIL Funding?
Accessing SIL funding usually involves several steps:
1. Functional Assessments
Health professionals assess support needs and daily living capacity.
2. Evidence Collection
Reports may include:
- Occupational therapy assessments
- Functional capacity assessments
- Behaviour support plans
- Medical documentation
3. SIL Quote and Roster of Care
A SIL provider develops a proposed support structure and staffing model.
4. NDIA Review
The NDIA reviews whether SIL funding is considered reasonable and necessary.
5. Approval and Matching
Once approved, participants can explore suitable SIL providers and housing options.
Common Misunderstandings About SIL Costs
- “The NDIS Pays My Rent”
Incorrect. SIL funds support services, not rent or daily living expenses.
- “Everyone Gets the Same SIL Budget”
Incorrect. Funding is highly individualised based on support needs.
- “SIL and SDA Are the Same Thing”
Incorrect. SDA refers to specialised housing, while SIL refers to support services within the home.
- “You Must Live in a Shared House”
Not always. Some participants may receive SIL funding while living alone if their support needs justify it.
Is SIL Worth It?
For many participants, SIL can significantly improve:
- Independence
- Daily routine
- Confidence
- Community participation
- Safety
- Social connection
- Life skills development
The goal of SIL is not simply to provide support. It is about helping participants live with greater choice, control, and independence.
Final Thoughts
SIL funding under the NDIS can seem complex at first, but understanding the difference between support costs and living expenses makes the process much clearer.
While participants still pay for everyday expenses like rent and groceries, SIL funding can cover the support services needed to live more independently and safely.
Because every participant’s situation is different, the best next step is usually speaking with an experienced SIL provider, support coordinator, or allied health professional who understands the NDIS home and living pathway.
If you are exploring Supported Independent Living options, understanding your funding early can help you make more confident decisions about your future independence.
FAQ

What does SIL funding cover?
SIL funding can cover support services that help a participant manage daily life and develop greater independence. Depending on their approved supports, this may include personal care, meal preparation, household tasks, medication assistance, life-skills development, community participation, supervision and overnight support.
How is SIL funding calculated under the NDIS?
SIL funding is based on the participant’s individual support requirements. A roster of care can be used to outline the type and amount of support required, including staffing ratios, active support hours, shared supports and overnight assistance. The participant’s circumstances and evidence are considered when determining whether the requested level of SIL support is reasonable and necessary.
Can I get SIL funding if I live alone?
Yes, it is possible to receive SIL support while living alone, but eligibility depends on the participant’s individual circumstances and support needs. SIL is intended for people who require regular assistance with daily living and need support to live more independently. The level and type of support must be appropriate to the participant’s needs and NDIS plan.
