Australia's national scheme funding supports for people with permanent and significant disability — ~774,000 active participants.

The Commonwealth agency that runs the NDIS: approves plans, sets price limits, publishes the quarterly data this platform is built on.

The independent regulator: registers providers, sets practice standards, runs audits, and takes compliance action (including banning orders).

A person with an approved NDIS plan. Plans specify funded supports by category; housing-related funding (like SDA) must be in the plan to be claimable.

An organisation registered with the NDIS Commission for specific registration groups. SDA payments can only be claimed by (or through) a registered SDA provider.

The NDIA's new CRM/payments system, rolled out from 2023 — changes how plans are structured and how funding is released (e.g. quarterly instalments in some cases).

Purpose-built or enrolled housing for participants with extreme functional impairment or very high support needs (~25,600 eligible people). Funds the bricks and mortar via an annual per-resident payment — separate from support services.

The five SDA building standards: Basic (existing/legacy stock only), Improved Liveability, Fully Accessible, Robust, and High Physical Support (the highest-priced). A dwelling is enrolled in one category; residents must be funded for a matching one.

Registering a specific dwelling with the NDIA as SDA, in a design category and building type. New builds must be certified against the SDA Design Standard by an accredited assessor first.

The official dwelling taxonomy with fixed resident counts — e.g. 'Apartment, 1 bedroom, 1 resident', 'House, 3 residents', 'Group Home, 5 residents'. Price limits are set per building type; resident counts are not negotiable inputs.

A dwelling configuration that includes space for overnight support staff (e.g. a separate room/apartment). Carries its own, higher base prices.

A published multiplier per SA4 region and building type applied to the base price. 'Median capital city' = 1.00; land-heavy building types range roughly 0.81–1.99 across regions.

The rent a SDA resident contributes: 25% of the Disability Support Pension base rate plus the maximum Commonwealth Rent Assistance. Paid to the provider on top of the NDIA's SDA payment.

Post-2023 new builds attract much higher price limits than enrolled existing stock; legacy stock (older group arrangements, 6-10 residents) is priced lower again and is being phased down.

Funded daily support (often 24/7, shared across residents) delivered in the home — the largest home-and-living payment pool. SIL is service funding to a support provider; it is not property revenue.

Short-stay / respite accommodation and support, typically up to 14 days at a time.

A flexible package for living arrangements like host families or co-residency — an alternative to SIL for lower support needs.

A funded role helping participants implement their plan — including finding housing. Support coordinators are a key channel for filling SDA vacancies.

The Social, Community, Home Care and Disability Services Industry Award (MA000100) — the award most disability support workers are employed under. Drives the labour costs in the Workforce Cost Modeller.

The ABS geographic unit the NDIA reports SDA data on — roughly a labour-market region. The NDIA's SDA tables cover 88 SA4 regions plus state-level 'Other' rows (96 rows total, as scored in Opportunity Score).

Council-level geography used in the NDIA's participant tables. Counts under 11 are suppressed for privacy.

The maximum a provider can claim for a support item or SDA place. Published by the NDIA; from 2026-27 most service price limits are national (state differentiation was removed).

The NDIA's quarterly data release (participants, payments, SDA supply and demand) — the primary public dataset behind this platform. Published ~45 days after each quarter ends.
