Reference period: -
Australia's population reached 27.7 million in the September 2025 quarter. Population growth has moderated to the pre-pandemic decade average of 1.6 per cent, following the strong rebound post-pandemic.
Over the year to September 2025, the population increased by 424,000 people. Of this, natural increase (births minus deaths) added 113,000, while net overseas migration added 311,000. Although annual natural increase is near its highest level since 2022, there are still fewer births and more deaths than prior to the pandemic. Annual net overseas migration increased for the first time in September 2025 since peaking in September 2023, but remains well below that peak.
