Darwin — LGA Conditions Intelligence

Darwin recorded negative net internal migration in every one of the four financial years to 2024–25 — the deepest and largest internal-migration outflow found anywhere in this series (−6,332 over four years, against Hobart’s −4,570). The outflow deepened from −979 (2021-22) to a peak of −2,047 (2023-24), then eased to −1,602 in 2024-25. Arrivals declined every year (9,374 → 7,431); departures rose then eased (10,353 → 9,729 → 9,834 → 9,033).

ERP growth segmented into four phases. Darwin’s phase labels invert relative to every other LGA built in this series: growth during the nominal “Stall” period (2009–2016, +11.1%) actually exceeded the “Boom” period (2001–2009, +10.3%), while the nominal “Recovery” period (2016–2021) is Darwin’s only negative phase (−0.5%) — a genuinely different trajectory shape from any LGA built so far, disclosed rather than forced into the standard phase narrative. The current phase (2021–2025, +6.1%) has since returned to growth.

Darwin’s total population is growing despite the internal-migration outflow above — the only mechanism of its kind found in this series. Positive natural increase (+2,747 over four years) and strong net overseas migration (+8,766 over four years, peaking at +2,669 in 2022-23) together outweigh the −6,332 internal loss, producing net ERP growth of +5,181 (84,854 → 90,035) since 2021. A migration-only read of Darwin would materially overstate population loss; overseas migration is the dominant driver of demand here, not internal relocation.

The Census unoccupied dwelling rate counts dwellings recorded as unoccupied on Census night — it is not a market vacancy rate. Darwin’s employed share (54.8%) and high-income share (16.7%) are both new series highs, ahead of Hobart’s prior highs (52.2% / 14.9%) — but Darwin’s age structure is the opposite of Hobart’s: younger (65+ at 11.0% vs Hobart’s 18.2%), far more renters (49.0% vs 31.5%) and far fewer outright owners (18.5% vs 30.4%), consistent with a working-age, high-mobility capital-city population rather than a retirement-shaped one.

• Bedrock figure is population-weighted, not a simple average of suburbs. Readings are on APN Bedrock™ methodology v1.1. Darwin’s population-eligible localities (78,979 residents across 34 localities) produce a population-weighted mean of 56.9 on node 24110. A simple, unweighted average gives 56.0 instead — a 0.9-point gap, one of the smallest found in this series. This card uses the population-weighted figure, consistent with the platform’s existing LGA-rollup convention.
• Classification badge is indicative, and does not fit this series’ existing four-way taxonomy cleanly. The “Reversing” label describes departure-led net internal migration, which Darwin matches exactly (0 of 4 years positive) — but the label was previously used for Hobart, where total population is genuinely declining. Darwin’s population is growing throughout, on overseas migration and natural increase rather than internal relocation. The badge is worded to disclose both facts rather than reuse Hobart’s label unqualified.
• No crime/safety data included in this version. APN Sentinel™ crime-pillar data (node 24121/24122) exists at suburb grain nationally but carries open, jurisdiction-specific data-quality caveats not yet resolved platform-wide — deliberately excluded from this card rather than presented with unresolved caveats attached.
• Demographic profile is 2021 Census vintage. Given internal migration has stayed negative and overseas migration strongly positive since, the population’s composition has very likely continued to shift.
• Card format approved 19 August 2026; the Bedrock population-weighting convention used above was adopted platform-wide in October 2026.
