Australia's population growth is influenced by natural increase (births minus deaths) and net overseas migration. Demographic projections indicate that Australia's population will continue to grow, with varying estimates for 2050. The 'Big Australia' term describes a potential increase to 35 million or more by 2050, with a projected median age increase to between 43.8 and 47.6 years. Population growth is expected to vary across states, with Western Australia projected to be the fastest-growing jurisdiction due to net overseas migration. This article will explore Australia's projected population growth by 2050 and the factors influencing it.

Population growth factors
Australia's population growth is influenced by various factors, including natural increase, net overseas migration, multicultural immigration, fertility rates, and mortality rates.
Natural increase, which is the difference between births and deaths, has been a significant contributor to population growth. In 2021-22, there were approximately 300,700 births and 183,300 deaths, resulting in a natural increase of 117,400 people. However, falling fertility rates have led to a decline in the rate of natural increase since 1962. The total fertility rate, or the average number of children per woman, is expected to continue decreasing, resulting in a natural increase falling below zero by the mid-2030s.
Net overseas migration, which is the difference between migrant arrivals and departures, also plays a crucial role in population growth. Multicultural immigration, particularly since World War II, has contributed to the growth of diverse religions and cultures in Australia. The European component of the population saw a sharp rise during the late 18th and 19th centuries, but its share is now declining. Capital cities have experienced a net loss from internal migration, impacting overall population distribution within the country.
Population projections by the Australian Bureau of Statistics indicate that Australia's population growth rate is expected to decline from the current ten-year average of 1.4% to between 0.2% and 0.9% by 2071. The population is projected to reach between 34.3 and 45.9 million people by 2071, with the median age increasing to between 43.8 and 47.6 years.
The Centre for Population also plays a vital role in producing population projections to inform policymakers and the public about Australia's future growth. These projections consider the latest demographic information and adjustments related to the COVID-19 pandemic. The Centre provides projections at the national, state, territory, capital city, and rest-of-state levels, with varying update frequencies.

State and territory projections
Australia's population growth is comprised of natural increase (births minus deaths) and net overseas migration (migrant arrivals minus migrant departures). The Australian Bureau of Statistics (ABS) provides population projections at the national, state, territory, and capital city levels. These projections are based on the latest demographic information and are adjusted to account for the impact of events like the COVID-19 pandemic. While these projections are not predictions, they illustrate the potential growth and changes in the population under different assumptions about future demographic trends.
Queensland
Queensland is projected to experience continuous growth over the projection period. By 2027, the state's population is expected to reach 6 million people. This growth can be attributed to factors such as fertility, life expectancy, and interstate and overseas migration flows.
Western Australia
By 2027, Western Australia's population is projected to increase to 3 million. The state's growth rate is influenced by similar factors as Queensland, including fertility, life expectancy, and migration patterns.
South Australia
South Australia is expected to have relatively slower growth compared to other states. By 2027, the population is projected to reach 2 million. This slower growth may be due to various demographic factors and migration trends unique to the state.
Australian Capital Territory
The Australian Capital Territory (ACT) is projected to experience notable growth. By 2027, the population is expected to be between 479,000 and 510,000. This growth could be influenced by the territory's attraction as a place to live and work, as well as migration patterns.
Tasmania
Tasmania's population is projected to reach between 545,000 and 573,000 people by 2027. This growth rate is similar to that of the ACT, and various factors contribute to it, including migration and the territory's unique demographic characteristics.
Northern Territory
The Northern Territory is projected to have a population of between 270,000 and 284,000 people by 2027. This growth rate is lower compared to other territories and states, and it is influenced by assumptions about fertility, life expectancy, and migration flows.
It is important to remember that these projections are based on assumptions about future trends and are subject to change. The actual population growth and figures may vary depending on various factors and unforeseen events.

Capital city projections
Australia's population growth is comprised of natural increase (births minus deaths) and net overseas migration. According to the Australian Bureau of Statistics (ABS), the country's population is projected to reach between 35.9 million and 38 million by 2050. This rapid growth is expected to be concentrated in major cities, with Sydney and Melbourne being the most populous. By 2046, Sydney's population is projected to reach 7.4 million, while Melbourne is expected to reach 7.3 million. Under the medium-growth model, Melbourne's population is expected to reach 8.5 million by 2050, while Sydney's will hit 8.3 million.
The capital cities are expected to experience significant population growth, with Sydney already having the highest overseas-born population among all capital cities in 2016, followed by Melbourne and Perth. The ABS also projected that growth would be fastest in Victoria, with the state expected to hit 7-8 million by 2027. By that time, Queensland's population is projected to increase to 6 million, Western Australia to 3 million, and Tasmania to 573,000, surpassing the Australian Capital Territory.
The rapid population growth in capital cities will have social and environmental implications. The Bureau of Infrastructure, Transport, and Regional Economics estimates that the "avoidable" social costs of traffic congestion in Australia's capital cities will increase significantly, impacting residents' quality of life. Additionally, the environment will be strained, particularly regarding greenhouse gas emissions. Australia's per capita emissions are already well above those of other developed nations, and accommodating a larger population will require tough mitigation measures to maintain current emission levels, let alone achieve the targeted reductions.

Fertility rates
Australia's population growth is determined by natural increase (births minus deaths) and net overseas migration (migrant arrivals minus migrant departures). In 2021-22, there were 300,700 births and 183,300 deaths, resulting in a natural increase of 117,400 people.
The number of births is projected to increase to between 284,700 and 482,700 births per year by 2071. This projection is based on three long-term assumptions regarding Australia's future total fertility rate (TFR): higher fertility (a TFR of 1.75 babies per woman), medium fertility (1.6), and lower fertility (1.45). Under all three assumptions, the trend toward older ages of mothers is assumed to continue to 2027, but at a slower rate than seen historically, and remain constant thereafter. For all years, the sex ratio at birth is assumed to be 105.5 male births per 100 female births.
In addition to fertility rates, mortality rates and migration patterns also play a significant role in population growth. The number of deaths in Australia is projected to reach between 378,200 and 402,800 by 2071. At the same time, migration continues to be a key factor in population growth, with net overseas migration contributing to the overall increase in population numbers.
The population projections by the Australian Bureau of Statistics are based on assumptions of fertility, mortality, and migration. These projections are not predictions or forecasts but illustrations of potential outcomes based on assumed levels of births, deaths, and migration between 2022 and 2071. The current ten-year average annual growth rate of 1.4% is projected to decline to between 0.2% and 0.9%.
The Centre for Population also plays a crucial role in producing population projections to inform policymakers and the public about Australia's future growth. They take into account demographic information and make adjustments for the impact of events like the COVID-19 pandemic. These projections are regularly updated to provide the most accurate estimates possible.

Migration
The impact of migration on Australia's economy and population growth is significant. Migration Solutions highlights that migration will drive employment growth, with a projected 15.7% increase in Australia's workforce participation rate. This is comparable to the rate of growth driven by women's participation in the workforce during the 20th century. Additionally, the Migration Council of Australia's report suggests that migration will make Australians better educated and more productive, with the economy expected to be a trillion dollars stronger by 2050.
The younger population within the migrant intake contributes to higher human capital. With 63% of migrants falling within the prime working age group of 25 to 44, the economy is forecast to grow by 40%. This trend is further supported by international students, primarily in the higher education sector, who provide the greatest economic benefit, according to Migration Solutions.
In terms of net overseas migration, the Australian Bureau of Statistics (ABS) reported a net gain of 445,640 people in 2023-24. This was a decrease from the previous year's record of 536,000 people. The impact of the COVID-19 pandemic and border restrictions caused a temporary reversal in migration trends in 2020 and 2021, with a net loss recorded during those years. However, the reopening of borders in February 2022 led to a period of record net overseas migration as arrivals caught up after the pandemic-related restrictions.
While the number of migrant departures increased by 8% to 221,000 in 2023-24, the overall trend suggests that more people migrate to Australia than leave each year, making overseas migration a significant contributor to the country's population growth.
