The September quarter of 2020 reset Australia’s population records – for the first time since World War I, the country’s population went backwards. It’s not surprising that this has been the result of international border closures, and in the September quarter alone, almost 35,000 more people left Australia than arrived. This resulted in the largest negative net overseas migraiton on record.
Those leaving Australia have generally been aged between 15 and 29 years of age. Many are international students who have completed their studies as would normally occur; only this time the outward flow hasn’t been offset by new arrivals. Ditto for working holiday makers.
The net outflow has resulted in a decrease in the number of 15 to 29 year olds living in Australia (compared to the year prior) for the first time in two decades.
