Tool № 08 · Aboriginal & Torres Strait Islander Health

Real per-LGA Indigenous population from Census 2021 — and an honest gap inventory.

The Aboriginal & TSI population in SNHN is 4,982 people (0.47% of the catchment, ABS Census 2021 — real per-SA2 counts aggregated to LGA). AIHW Indigenous Health Performance Framework, MBS 715 uptake, Indigenous chronic-disease prevalence, screening participation, and life-expectancy gap are published at national / state level only. We disclose those gaps rather than apply national rates to local Indigenous populations.

§ 01 · By LGA

Indigenous population per LGA — and top SA2s.

All values are real per-SA2 ABS Census 2021 counts. Top-3 SA2s by Indigenous population shown for each LGA — the candidates for ACCHO partnership prioritisation and culturally-safe service design.

§ 02 · Public-data inventory

What AIHW publishes per PHN by Indigenous status — and what isn't.

AIHW Indigenous HPF, MBS 715, Indigenous chronic-disease prevalence, screening, suicide, life-expectancy — all national-only. We disclose, we don't fabricate per-PHN figures.

AIHW publishes per-PHN childhood immunisation with Indigenous flag — Tool 17 shows the general per-PHN figure already; the Indigenous breakdown table isn't ingested in our schema yet.

AIHW Indigenous HPF

Published at national level (sometimes state). Per-PHN figures by Indigenous status are not published — applying national rates to local Indigenous population is modelling, intentionally omitted.

How to fill these gaps · Internal-data tier

Record-level extracts + ACCHO partnerships — real per-PHN Aboriginal & TSI health indicators in 4-6 weeks.

MBS record-level extracts → real per-PHN Item 715 uptake by LGA and age
POLAR / PenCS GP extracts → real GP-recorded Indigenous-status flags + chronic-disease registers
AIHW disaggregated Indigenous HPF ingest → state-PHN crosswalk where AIHW publishes it
Local ACCHO data-sharing partnerships → ACCHO-recorded service utilisation, screening rates

Data quality notes

Indigenous population per LGA is real ABS Census 2021 — no modelling.
AIHW Indigenous HPF publishes at national level only — applying those rates to PHN Indigenous populations is modelling, intentionally omitted.
MBS 715 uptake per PHN is not in public MBS Item Statistics — internal-data tier required.
AIHW does publish per-PHN childhood immunisation with Indigenous status; we'll surface that in the next ingest cycle.
Indigenous-status under-reporting in MBS/AIHW collections is a documented data-quality issue — any per-PHN figure derived from these would carry that floor/ceiling caveat.
