Australia’s population grew by 1.6 per cent in the year to 31 March 2025 to an estimated 27.5 million, according to the Australian Bureau of Statistics (ABS).
ABS data show the population increased by 423,400 over the year, with overseas migration adding 315,900 people and natural increase (births minus deaths) contributing 107,400. Both births and deaths registered in Australia rose by 2.1 per cent. Overseas migration was down from 493,800 in the previous 12 months — a fall of about 178,000 people, or 36 per cent — meaning around three-quarters of the year’s growth came from migration.
Western Australia recorded the fastest population growth of the states and territories at 2.3 per cent, the ABS said. Victoria and Queensland were equal second at 1.8 per cent. Tasmania had the slowest growth at 0.2 per cent.
