Where the Data Comes From
Net Overseas Migration (NOM) data — the number of people who add to or subtract from Australia's population through international migration. Broken down by country of birth, visa group, state/territory, age, and sex. Published approximately 3 months after each quarter end. The ABS uses the "12/16 month rule" — a person is counted as a migrant arrival if they stay in Australia for 12+ months within a 16-month period.
→ ABS Overseas Migration (3412.0) — Latest Release
Monthly count of all movements through Australian air and sea ports by traveller category (short-term visitor, student, temporary resident, settler), visa group, country of citizenship, and state of clearance. Published with a 6–8 week lag. Note: this counts movements, not unique people — a person entering twice is counted twice.
→ ABS Overseas Arrivals & Departures (3401.0) — Latest ReleaseHome Affairs publishes several key datasets: the annual Migration Program outcomes (permanent visa grants by stream — Skilled, Family, Humanitarian, Special Eligibility); the Temporary Entrants Program (quarterly snapshot of all temporary visa holders in Australia); Overseas Arrivals & Departures by visa group; and immigration detention statistics (updated regularly).
