Nine LGAs along the harbour-and-bushland spine. 931,439 people. The data layer for commissioning care across the catchment — built from Census, ABS, AIHW, ACARA, DSS and ATO sources, refreshed on cadence.
Every one of SNHN's nine LGAs sits in IRSD decile 10 nationally. The disadvantage frame doesn't fit. The planning frame that does fit is ageing and care load — 56,100 age pensioners and 10,790 on the DSP, with the share aged 65+ ranging from 12.4% (Lane Cove, Ryde) to 18.3% (Mosman).
All nine LGAs at decile 10. Yet within that decile, IRSD raw scores still span 55 points — from Ryde (1055) to Mosman (1110). Treat the catchment as uniform and you'll miss where care need actually clusters — in the older corners (Mosman, Hunters Hill) and the lower-IRSD corners (Ryde, Willoughby).
Source · ABS SEIFA 2021 · 9 LGAs · IRSD raw score range 1055–1110Five AIHW datasets, all real per-PHN values straight from the public releases — no national rates applied locally, no modelled fill-ins. Childhood immunisation + practice-quality (PIP-QI) come direct from the AIHW PHN release; AOD treatment episodes from the AODTS NMDS; hospital activity from MyHospitals (Northern Sydney LHN, co-extensive with SNHN's footprint); and preventable hospitalisations from AIHW PPH (state-aggregated — we show that honestly). Adult immunisation, MORT suicide rates, and Mothers & Babies sit in each tool's data inventory below, queued for the next ingest.
A 7.8 pp First Nations gap at 5-year-olds — fully-immunised rate 86.15% vs 93.91% overall.
On urgent-triage performance SNHN runs +7pp ahead of National (68% vs 61%) — but 4-hour ED throughput trails by 2pp.
Treatment episodes peaked at 3,437 in 2020-21 — pandemic-era — and have since settled 14% lower.
Vaccine-preventable PPH at 250/100k vs 2,219/100k total — the largest single lever.
BMI recorded in only 19.8% of practices — lowest of all indicators. HbA1c and BP sit near 50%.
Every dataset that AIHW, ABS, ACARA, DSS, NDIS, or state agencies publish per PHN or per LGA — surfaced for SNHN's nine LGAs. Where a metric isn't published per PHN, the tool says so honestly.
ABS ERP age × sex per LGA — 2024 latest. 17.6% aged 65+ across the catchment.
IRSD/IRSAD/IER/IEO at LGA level. All 9 SNHN LGAs at decile 10 — variance is in the raw scores (1055–1110).
268 schools, 153,466 enrolments in catchment. ACARA latest with ICSEA, sector, LBOTE %.
397,804 ABN-registered businesses in catchment; 46,650 new in last 12 months. Health-sector filter TBC.
Public-transport reach per LGA from TfNSW GTFS — frequency, route density, distance-to-care signals.
Rent, mortgage, and housing-stress signals from Census 2021 — a social determinant your commissioning team can plan against.
Honest inventory — AIHW doesn't publish per-PHN MH prevalence. We disclose, we don't fabricate.
Real per-LGA Indigenous population counts from Census 2021. AIHW Indigenous HPF national-only — disclosed.
Real per-LGA born-overseas, LBOTE, ancestry from Census 2021. Top CALD cohorts per LGA, real counts.
Real per-LGA 65+/75+/85+ counts from ABS ERP 2024. Provider locations via My Aged Care.
Real per-PHN AODTS treatment-episode counts + substance + treatment-type mix. AIHW 2023-24.
SA2-level commissioning composite from real Census 2021 inputs. Not a clinical instrument.
Real per-LGA children-0-14 and women-15-49 cohort counts. AIHW Mothers & Babies national-only — disclosed.
Honest gap — MBS after-hours items not published per PHN. Internal-data tier required.
Real per-PHN AIHW PIP-QI 10-indicator set — practice-recorded BMI, HbA1c, smoking, BP, screening.
My Health Record + telehealth signals. Real population denominator from ABS ERP.
Real per-PHN AIHW immunisation Q4 2024 — 1yr / 2yr / 5yr fully-immunised, with First Nations gap.
Honest gap — AIHW publishes screening rates at SA3, not per PHN. Eligible populations from ABS ERP.
AIHW PPH 2023-24 — state-aggregated. We show that honestly with the "AIHW publishes at state level" callout.
AIHW publishes BoD national/state only. Real ABS ERP age structure forms the denominator.

SNHN's portal was built in two weeks from public data + their LGA list. Yours can too — same shape, your colours, your data sources. From A$5k starter.
Behind the demographics. Where care need actually clusters.
SA2-level Census aggregated to SNHN's nine LGAs via the ABS concordance. Counts are overlap-weighted sums; medians are population-weighted across contributing SA2s.
A major CALD signal for service design — interpreter capacity, in-language health literacy, and culturally-safe care all start here.
High educational attainment shifts the commissioning lens — health-literacy is high, but mental-health and ageing care need different framing here.
High housing-cost pressure even at high incomes — the affordability ratio matters for vulnerable cohorts and influences workforce-housing decisions.
Income skews high — SEIFA decile 10 across all nine LGAs. The disadvantage frame doesn't fit; the planning frame is ageing + care load.
