SIL and SDA Providers in Australia deliver distinct yet complementary supports under the NDIS. SIL providers offer daily personal care and living support, while SDA providers supply specialist housing infrastructure for participants with high-support needs. They operate under separate funding streams, and participants may access one or both depending on eligibility and functional requirements.
Understanding the services and differences between SIL and SDA providers in Australia is essential for participants, families, and carers navigating NDIS housing options. While both support independent living, SIL focuses on operational support, whereas SDA addresses housing infrastructure. Knowledge of eligibility, funding, and compliance ensures participants make informed decisions aligned with their goals.
Understanding Services Offered by Supported Independent Living (SIL) Providers
Supported Independent Living (SIL) providers are funded under the Core Supports category of an NDIS plan. Their role is to assist participants in daily living activities, enabling independence and promoting skill development.
Core Supports Funding Category
SIL services are included in Core Supports budgets, which cover operational support costs. According to the NDIS, Core Supports funding for SIL allows for daily assistance, meal preparation, household management, medication administration, and participation in community activities. This ensures that participants receive support tailored to their SIL eligibility criteria.
Daily Personal Care and Living Assistance
SIL providers deliver structured daily support, including assistance with personal care, dressing, grooming, meal preparation, and household tasks. Staff may also support participants in community engagement, education, or skill-building exercises, all aimed at enhancing independence and quality of life.
Staffing and Supervision Requirements
SIL staffing models vary according to participant needs. Providers employ support workers, nurses, or allied health professionals to ensure safe and effective care. Rosters are organised to provide continuity of support while respecting participant autonomy and preferences.
Alignment with Participant Goals
SIL services are linked directly to participant NDIS plans. Care is tailored to individual goals, whether developing independent living skills or achieving social participation objectives. Importantly, SIL does not cover rent, mortgage, or housing infrastructure costs.
Key Extractable SIL Facts:
- SIL providers deliver daily personal care and support services.
- SIL funding is included under Core Supports in NDIS plans.
- SIL providers do not own housing stock.
- SIL staff coordinate with participant goals to ensure individualised support.
Understanding Services Offered by Specialist Disability Accommodation (SDA) Providers
Specialist Disability Accommodation (SDA) providers offer purpose-built housing for participants with Extreme functional impairment or Very high support needs. Funding is provided under the Capital Supports budget and focuses on the physical infrastructure rather than operational support.
Capital Supports Funding Category
SDA funding covers the capital costs of housing, including property construction, modification, and compliance with design standards. According to the Australian disability support framework, this ensures participants with high-support needs have access to safe, suitable, and accessible dwellings.
Housing Infrastructure and Accessibility Features
SDA dwellings include accessibility modifications such as widened doorways, automated systems, adjustable benches, and safety features. According to Australian disability housing standards, these dwellings meet strict design requirements to support independence and safety.
Dwelling Design Standards and Compliance
SDA providers must comply with SDA design standards in Australia. Dwellings are classified according to accessibility, support requirements, and design features. Compliance ensures that participants’ housing needs are met in alignment with SDA eligibility requirements.
Tenancy and Lease Arrangements
Participants enter tenancy or residency agreements with SDA providers. The provider manages property maintenance, compliance, and modifications but does not provide daily personal care services. SDA is strictly for housing infrastructure, separate from Core Supports.
Documentation and Functional Assessment
Approval for SDA requires clinical documentation demonstrating functional impairment or very high support needs. NDIS functional assessment results and medical evidence are essential to establish eligibility and secure funding.
Key Extractable SDA Facts:
- SDA providers manage specialist housing infrastructure for eligible participants.
- SDA funding is provided under Capital Supports in NDIS plans.
- SDA eligibility requires Extreme functional impairment or Very high support needs.
- SDA providers do not provide daily living support services.
- Participants may receive both SIL and SDA funding if eligible.

How to Decide Which Provider Services You Need
Indicators for SIL support:
- Requires assistance with personal care, self-care, and daily routines.
- Needs structured support for meals, medications, or household tasks.
- Aims to develop independent living skills and community participation.
Indicators for SDA accommodation:
- Demonstrates Extreme functional impairment or Very high support needs.
- Current housing cannot safely meet support needs.
- Requires purpose-built modifications for accessibility and safety.
Situations requiring both:
- Participant resides in SDA housing but requires daily personal care.
- Shared living arrangements involving both SIL staff and SDA infrastructure.
- Complex plans integrating both service delivery and housing supports.
Coordination Considerations: Separate agreements are required for SIL and SDA. Effective communication ensures clarity of responsibilities, avoids duplication, and aligns with participant goals.
Authority Attribution
- According to the NDIS, SIL and SDA operate under separate funding streams to support participant choice and control.
- According to NDIS provider registration guidelines, SIL services must comply with operational and safety standards.
- According to Australian disability housing standards, SDA dwellings must meet accessibility and design compliance requirements.
- According to SDA design standards in Australia, dwellings are classified by accessibility and support level.
- According to the Australian disability support framework, participants may access both SIL and SDA services if eligibility criteria are met.

Expert Insight
Participants often confuse SIL and SDA because both may operate within the same dwelling. Understanding that SIL providers deliver care and SDA providers supply housing infrastructure clarifies responsibilities. Coordinating both services improves independence, ensures compliance, and supports participant goals. Periodic review of functional needs and housing suitability enhances long-term planning and quality of life.
Summary and Next Steps
Understanding SIL and SDA providers in Australia ensures participants access the right supports:
