In 2050, Melbourne would be expected to reach 8.5 million while Sydney's population would have hit 8.3 million under the medium-growth model.
The populations of Sydney and Melbourne are forecast to swell by 60 to 80 per cent to reach about 8 million by 2050, while Perth's population is poised to more than double to 4.6 million. In addition, the profile of the Australian population is altering and ageing.
Between 2011 and 2021, Melbourne had the largest growth (up by 806,800 people), followed by Sydney (650,800) and Brisbane (421,500). Canberra had the highest growth rate (23%), followed by Brisbane and Perth (both 20%).

Australia is ranked 1st among 23 countries in Oceania. Australia's population will be increased year by year. The Australia population is projected to reach 28.18 million in 2030 and increase further to 32.81 million in 2050 and 42.88 million by 2100.
While Sydney is currently Australia's largest city, Melbourne is closing the gap and in the month of September 2030, will overtake Sydney to become Australia's largest city by population. Such has been Melbourne's growth, it reached a population of five million in 2018, two years after Sydney hit the milestone.
In 2050, Melbourne would be expected to reach 8.5 million while Sydney's population would have hit 8.3 million under the medium-growth model.
Future cities
A report by Infrastructure Australia states that in the coming 30 years, Perth, along with Brisbane, will experience fundamental change, with each growing to the size of Melbourne and Sydney today. Perth will surpass Brisbane as Australia's third largest city.
Perth city lies at the heart of Greater Perth, which is home to just over two million people or 77 per cent of the state's population. This is forecast to grow to 2.9 million people by 2031 and 3.5 million people by 2050, becoming the third largest city in Australia after Sydney and Melbourne.
Accounting for almost half of Australia's economic growth, Sydney offers the best job prospects for expats moving to Aus. With an unemployment rate well below the national average at around 3.8%, Sydney has a booming economy in industries such as financial and professional services, construction and manufacturing.
Living in Melbourne
Melbourne is considered by some to be the best city to live in Australia, and has even been ranked as the world's most livable city more than once. It's home to a thriving live music scene, late-night bars and laneways dotted with cafés and coffee shops.
While many people have already moved to Tasmania to escape the heat in other states, some doomsday preppers are weighing up the island state as a post-apocalyptic option. Tasmania scored highly in the report in terms of its climate, electricity supply, agricultural resources and population density.
Michigan, says globalization expert. A new book examining the forces shaping the future of global migration forecasts Michigan as the best place in the world to live in 2050.
In 2018, a report by Infrastructure Australia predicted that Perth, within 30 years, would grow to be the same size Melbourne and Sydney were in that year and surpass Brisbane as Australia's third largest city.
Queensland had the fastest growing population over the year to March 2022, followed by Western Australia and South Australia. Annual population growth in New South Wales and Victoria increased from the previous quarter, while growth in the Northern Territory was slow but positive.
Will Perth property prices rise in 2023? Yes. The demand/supply fundamentals for growth in Perth are as strong as ever, with demand nominally stronger than the mining boom. Supply is tighter, both in the sales and rental market, than any time in the last 20 years.
Based on federal data, social researcher Mark McCrindle forecasts that Melbourne will overtake Sydney as the nation's biggest metropolis on September 7, 2030, with a population of about 5.8 million.
More recent data sourced from the ABS indicates that the tide is turning and that Melbourne is forecasted to be Australia's fastest-growing city over the next 10 years.
China is expected to hold on to the number one spot. In 2050, the Asian giant is forecast to have the largest economy on the planet. With an ageing population and an annual GDP growth rate averaging just 4.4%, however, China isn't projected to enjoy the exceptional economic growth it experienced during the 2000s.
China, India, and the United States will emerge as the world's three largest economies in 2050, with a total real U.S. dollar GDP of 70 percent more than the GDP of all the other G20 countries combined. In China and India alone, GDP is predicted to increase by nearly $60 trillion, the current size of the world economy.
The chart below shows the resulting share of global GDP for several major regions in the year 2100. In the univariate model, China will be the largest economy in the world in 2100, producing some 27% of global output.
