Coverage figures shown are from AIHW's PHN Immunisation Coverage Q3 2025 release. AIHW publishes coverage per PHN, at three age points (1yr / 2yr / 5yr) — these are the only real per-PHN immunisation values currently available. Adult cohort coverage (HPV at 15, flu 65+, COVID booster 65+, pneumococcal 65+) is not published per-PHN by AIHW and is intentionally not shown. Absolute child counts under target need birth-cohort denominators per PHN, also not in this release. Per-LGA detail requires AIR record-level extraction (Domato internal-data tier).
