New data reveals that Sydney is experiencing a major population shift, with housing affordability at the heart of the exodus.

Between 2021 and 2024, more than 129,000 residents left Sydney for other parts of the country, the highest internal migration loss of any capital city.

In the last financial year alone, 41,000 people relocated, outweighing the city’s natural population growth.

For those focused on residential property investing in Australia, this trend highlights shifting demand away from high-cost urban centres.

While Melbourne and Darwin also saw population declines, cities like Brisbane, Perth, and regional Queensland recorded strong gains.

Brisbane welcomed 56,100 newcomers, with regional Queensland close behind at 54,900, and Perth attracting 27,500.

The e61 Institute points to housing costs as the key driver, especially among Australians in their 30s.

As Sydney’s median home prices remain unaffordable for many, younger buyers and renters are seeking value in more affordable markets, where lifestyle and opportunity intersect.

However, the migration wave may soon slow. Property prices in Brisbane and regional Queensland are rising, gradually narrowing the affordability gap with Sydney.

With lifestyle preferences, demographics, and affordability all reshaping migration patterns, the opportunity for smart, strategic property investing is expanding beyond traditional metro markets.
