NDIS participants with high support needs have several accommodation pathways beyond living with family. Understanding the differences between SIL, SDA, ILO, and other options helps you choose the right living arrangement for your goals and needs.
Key Points
- SIL (Supported Independent Living) funds 24/7 support workers, not the building
- SDA (Specialist Disability Accommodation) funds the specialized building, not support
- ILO (Individualised Living Options) offers customized arrangements with maximum choice and control
- You can have SIL without SDA, SDA without SIL, or both together depending on needs
- Medium-Term Accommodation provides temporary housing for up to 90 days during crises
- Short-Term Accommodation (respite) gives carers breaks and participants skill development opportunities
- Most NDIS participants live in standard housing with lower-intensity supports, not SIL or SDA
Overview of NDIS Accommodation Supports
NDIS funds various accommodation options depending on support intensity required.
| Accommodation Type | What It Funds | Who It’s For | Typical Annual Funding |
|---|---|---|---|
| SIL (Supported Independent Living) | 24/7 support workers | Very high support needs requiring around-the-clock assistance | $180,000-$400,000 |
| SDA (Specialist Disability Accommodation) | High-spec accessible building rent | Extreme functional impairment requiring specialized housing features | $60,000-$100,000 |
| ILO (Individualised Living Options) | Custom support arrangements designed specifically for you | People wanting maximum control over living arrangements | Varies widely |
| Short-Term Accommodation | Temporary stays for respite or skill development | Anyone needing carer breaks or independence training | $5,000-$30,000 |
| Medium-Term Accommodation | Temporary housing during crises (max 90 days) | People experiencing housing crisis or transition | $15,000-$50,000 |
| Standard housing + supports | Regular Support Worker visits | Majority of participants with lower support needs | Varies |
Supported Independent Living (SIL) in Detail
SIL funds support workers to assist with daily living tasks 24/7.
What SIL Covers
- Personal care (showering, toileting, dressing)
- Meal preparation and assistance with eating
- Medication management and health monitoring
- Household tasks (cleaning, laundry)
- Community participation support
- Skill development and independence training
SIL Eligibility
You need very high support needs that cannot safely be met with less than 24/7 assistance. Typical SIL participants have:
- Severe intellectual disability requiring extensive support
- High support physical disabilities requiring full assistance with ADLs
- Complex disabilities with combined cognitive and physical support needs
- Acquired brain injury with ongoing high support requirements
SIL Arrangements
Shared SIL:
- 2-6 participants share a house with rostered support staff
- Support costs shared between residents, lowering per-person funding
- More social connection with housemates
- Less privacy and flexibility
Individual SIL:
- You have dedicated support staff (1:1 arrangements)
- Much higher costs ($300,000-$500,000+ annually)
- Maximum privacy and control
- Harder to justify as reasonable and necessary unless extreme needs
SIL Funding Process
- Request SIL assessment at planning meeting or plan review
- Independent assessment of support needs
- Plan variation to add SIL funding to Home and Living budget
- Find SIL provider with vacancy
- Transition planning and move
Specialist Disability Accommodation (SDA) in Detail
SDA funds the building with specialized accessibility features.
What SDA Covers
SDA rent-equivalent funding for buildings with features such as:
- Ceiling hoists for transfers
- Fully accessible bathrooms with roll-in showers
- Widened doorways and corridors
- Adjustable height kitchens
- Smart home environmental controls
- Reinforced walls and fittings (robust category)
- Emergency backup power
SDA Design Categories
Improved Liveability:
- For sensory, intellectual, or cognitive disabilities
- Better acoustics, lighting, spatial layout
- Typical funding: $45,000-$65,000/year
Fully Accessible:
- For high physical support needs, wheelchair users
- Ceiling hoists, accessible bathrooms, wide doorways
- Typical funding: $60,000-$90,000/year
Robust:
- For complex challenging behaviors
- Reinforced walls, impact-resistant fixtures
- Typical funding: $65,000-$95,000/year
High Physical Support:
- Combination of Fully Accessible + Robust
- Extreme physical and behavioral needs
- Typical funding: $80,000-$120,000+/year
SDA Eligibility
Only ~6% of NDIS participants qualify. You need extreme functional impairment requiring specialized housing features that:
- Cannot be achieved through home modifications to standard housing
- Substantially improve your living situation
- Represent value for money compared to alternatives
SDA Assessment
Complete SDAT (SDA Decision Tool) assessment with independent occupational therapist to determine eligibility and appropriate design category.
Individualised Living Options (ILO) in Detail
ILO is a philosophy more than a specific program, emphasizing maximum choice and control in living arrangements.
What ILO Means
ILO arrangements are custom-designed for you or a small group you choose. You decide:
- Where you live (location and property type)
- Who you live with (choosing housemates or living alone)
- What support model you use (rostered staff, live-in support, combination)
- Your daily routines and household operations
ILO vs Traditional SIL
| Feature | Traditional SIL | ILO |
|---|---|---|
| Who designs arrangement | Provider determines setup | You design with provider support |
| Housemate selection | Provider matches participants | You choose housemates or live alone |
| Location | Provider’s existing properties | You choose location |
| Support model | Standard rostered shifts | Customized to your preferences |
| Flexibility | Structured routine | High flexibility |
| Complexity | Provider manages | Requires active participant involvement |
ILO Funding
ILO uses the same funding mechanisms as SIL (24/7 support funded through Home and Living budget). The difference is how supports are delivered, not funding amount.
ILO may cost more initially due to setup costs, property search, and custom arrangement design. However, long-term costs can be comparable to traditional SIL.
Who ILO Suits
ILO works best for participants who:
- Have clear preferences about living arrangements
- Want maximum control over housemates, location, and routines
- Can engage in planning and design process (or have strong family/advocate support)
- Are willing to accept the complexity of custom arrangements
- Have support needs requiring 24/7 assistance (ILO is not for lower support needs)
Creating an ILO
- Secure SIL-level funding in your plan (same as traditional SIL)
- Work with Support Coordinator or specialist ILO facilitator to design arrangement
- Find property in desired location
- Recruit housemates if shared arrangement
- Engage support provider willing to deliver customized model
- Transition into arrangement with ongoing refinement
ILO development takes 12-24+ months from concept to move-in.
Short-Term Accommodation (STA / Respite)
Short-Term Accommodation (previously called respite) provides temporary stays away from your usual residence.
Purposes of STA
Carer respite:
- Gives family carers breaks to prevent burnout
- Allows carers to travel, attend events, or simply rest
Skill development:
- Practice independence skills in supported environment
- Gradual transition preparation for SIL or ILO
- Building confidence in new settings
Emergency backup:
- When usual carers are ill or unavailable
- During household emergencies or crises
STA Types
Facility-based STA:
- Purpose-built respite facilities
- Staff on-site 24/7
- Group living environment
- Structured programs and activities
Host family STA:
- Staying with another family
- Home environment setting
- More personalized, less institutional
- Better for children and young adults
In-home STA:
- Support workers stay at your home while family carers leave
- Maintains routine and familiar environment
- Reduces disruption for participant
STA Funding
STA is funded through Core Supports budget and is flexible (you control how much respite to use).
Typical allocation: $5,000-$30,000/year depending on carer support needs. Rates vary by STA type and intensity.
Medium-Term Accommodation (MTA)
MTA provides temporary housing for up to 90 days when you cannot live in your usual residence due to crisis.
When MTA is Used
- Family relationship breakdown requiring immediate alternative housing
- Homelessness or risk of homelessness
- Waiting for SIL or SDA property to become available
- Recovery from abuse, neglect, or exploitation
- Transition from institution or hospital to community
MTA vs STA
MTA is for housing crises, while STA is for planned respite. MTA typically lasts weeks to months, STA lasts days to weeks.
MTA Funding
Funded through Core Supports with specific MTA line item. Costs vary widely depending on accommodation type and support intensity required.
MTA is transitional. During your MTA stay, your team works on permanent housing solution.
Standard Housing with Supports
Most NDIS participants (94%) live in standard housing (private rental, own home, family home) with support visits rather than 24/7 arrangements.
Support Options for Standard Housing
Regular Support Worker visits:
- Few hours daily or several times weekly
- Assistance with specific tasks (personal care, meal prep, community access)
- Funded through Core Supports
Home modifications:
- Ramps, grab rails, accessible bathrooms
- Funded through Capital Supports
- Enables independent living in standard housing
Assistive technology:
- Equipment supporting independence
- Communication devices, mobility aids, smart home tech
- Reduces reliance on human support
This approach suits participants with lower support needs who can manage most daily tasks independently or with family support.
Choosing the Right Accommodation Option
Consider your support needs, independence goals, financial situation, and personal preferences.
Decision Framework
Choose traditional SIL if:
- You need 24/7 support for safety and daily living
- You want established provider with infrastructure
- You are comfortable with shared living in provider-selected housemates
- You want straightforward access to proven model
Choose ILO if:
- You need 24/7 support but want maximum control
- You have strong preferences about location, housemates, routines
- You can engage in complex planning process
- You are willing to wait for custom arrangement development
Choose SDA if:
- Your functional impairment is extreme requiring specialized building features
- Standard home modifications cannot address accessibility needs
- Specialized features substantially improve your living capacity
Choose standard housing with supports if:
- Support needs are manageable with less than 24/7 assistance
- You can live independently or with family support plus Support Worker visits
- Home modifications make standard housing accessible enough
Use STA for:
- Regular carer breaks
- Independence skill development
- Emergency backup when usual supports unavailable
Use MTA for:
- Housing crises requiring immediate alternative accommodation
- Transitions between permanent housing arrangements
Combining Accommodation Supports
You may need multiple accommodation support types depending on circumstances.
Common Combinations
SIL + SDA:
- Very high support needs + extreme functional impairment
- Full package for most intensive requirements
- Total funding: $240,000-$500,000+ annually
SIL only (in standard housing):
- Very high support needs
- Standard housing accessible enough without SDA
- Common arrangement, lower cost than SIL + SDA
SDA only (without SIL):
- Extreme functional impairment requiring specialized housing
- Support needs met with less than 24/7 assistance
- Assistive technology or part-time supports sufficient
Standard housing + regular STA:
- Live at home with family
- Regular respite gives family carers sustainable breaks
- Gradual skill building for future independent living
FAQ
Can I switch from SIL to ILO mid-plan?
Yes, though it requires significant planning. Work with Support Coordinator to design ILO, find property and housemates, engage provider, and transition. Funding amount should remain similar (both use SIL-level funding) but delivery model changes.
How do I know if I need SDA, SIL, both, or neither?
Request comprehensive occupational therapy assessment evaluating functional capacity and support needs. OT can recommend whether you need specialized housing (SDA), 24/7 support (SIL), both, or standard housing with modifications and part-time supports.
What if I want to live alone but need 24/7 support?
Individual SIL allows this but is expensive ($300,000-$500,000+ annually). NDIA carefully scrutinizes individual SIL for value for money. Strong justification needed for why shared SIL cannot meet your needs.
Can I trial SIL before committing long-term?
Yes. Use Short-Term Accommodation to stay at SIL providers for trial periods (weekends or weeks). This helps you assess whether SIL suits you and compare different providers.
What happens if SIL provider closes or I’m unhappy with service?
You can change SIL providers. Your funding is portable. Find new provider with vacancy, arrange transition, and move. Give current provider appropriate notice per your service agreement (typically 4-8 weeks).
Is ILO more expensive than traditional SIL?
Setup costs are higher due to property search, custom arrangement design, and provider training. Ongoing costs are similar to SIL once established. Some participants find ILO represents better value through improved outcomes.
Can family members continue involvement if I move to SIL or ILO?
Absolutely. Quality SIL and ILO arrangements welcome family involvement at level you prefer. Family can visit, participate in decision-making, stay informed about your wellbeing, and maintain whatever relationship you want.
What’s the maximum STA funding I can get?
There is no hard cap, but typical allocations are $5,000-$30,000/year. If your family carers need extensive respite to prevent burnout, request higher STA funding at plan review with evidence from GP or therapist about carer stress.
