Historical dataset of population level and growth rate for the Sydney, Australia metro area from 1950 to 2026.

As of June 2025, it was estimated that around 7.3 percent of Australians were aged between 25 and 29, and the same applied to people aged between 35 and 39. All in all, 55 percent of Australia’s population was aged 35 years or older as of June 2025. At the same time, the age distribution of the country also shows that the share of children under 14 years old was almost the same as the share of people over 65 years old. A breakdown of Australia’s population growth Australia is the seventh-largest country in the world, yet with a population of around 27.6 million inhabitants, it is only sparsely populated. Since the 1970s, the population growth of Australia has remained fairly constant. While there was a slight rise in the Australian death rate in 2022, the birth rate of the country decreased after a slight rise in the previous year. The fact that the birth rate is almost double the size of its death rate gives the country one of the highest natural population growth rates of any high-income country.
National distribution of the population Australia’s population is expected to surpass 29 million people by 2030. The majority of its inhabitants live in the major cities. The most populated states are New South Wales, Victoria, and Queensland. Together, they account for over 75 percent of the population in Australia.

Humans have been living on the continent of Australia (name derived from "Terra Australis"; Latin for "the southern land") for approximately 65,000 years, however population growth was relatively slow until the nineteenth century. Europeans had made some contact with Australia as early as 1606, however there was no significant attempt at settlement until the late eighteenth century. By 1800, the population of Australia was approximately 350,000 people, and the majority of these were Indigenous Australians. As colonization progressed the number of ethnic Europeans increased while the Australian Aboriginal population was decimated through conflict, smallpox and other diseases, with some communities being exterminated completely, such as Aboriginal Tasmanians. Mass migration from Britain and China After the loss of its American colonies in the 1780s, the British Empire looked to other parts of the globe to expand its sphere of influence. In Australia, the first colonies were established in Sydney, Tasmania and Western Australia. Many of these were penal colonies which became home to approximately 164,000 British and Irish convicts who were transported to Australia between 1788 and 1868. As the decades progressed, expansion into the interior intensified, and the entire country was claimed by Britain in 1826. Inland colonization led to further conflict between European settlers and indigenous Australians, which cost the lives of thousands of natives. Inward expansion also saw the discovery of many natural resources, and most notably led to the gold rushes of the 1850s, which attracted substantial numbers of Chinese migrants to Australia. This mass migration from non-European countries eventually led to some restrictive policies being introduced, culminating with the White Australia Policy of 1901, which cemented ethnic-European dominance in Australian politics and society. These policies were not retracted until the second half of the 1900s. Independent Australia Australia changed its status to a British dominion in 1901, and eventually became independent in 1931. Despite this, Australia has remained a part of the British Commonwealth, and Australian forces (ANZAC) fought with the British and their Allies in both World Wars, and were instrumental in campaigns such as Gallipoli in WWI, and the South West Pacific Theater in WWII. The aftermath of both wars had a significant impact on the Australian population, with approximately 90 thousand deaths in both world wars combined, as well as 15 thousand deaths as a result of the Spanish flu pandemic following WWI, although Australia experienced a significant baby boom following the Second World War. In the past fifty years, Australia has promoted immigration from all over the world, and now has one of the strongest economies and highest living standards in the world, with a population that has grown to over 25 million people in 2020.

The value of commercial building activity in Australia was forecasted to amount to around **** billion Australian dollars in the 2025 fiscal year. This was around the same as the commercial building activity value as of fiscal year 2019, which reached over **** billion Australian dollars.

Commercial building activity boom

The short-term increase in commercial building activity was attributable to strong employment and population growth. Buildings such as shops, hospitals, cafes, restaurants, schools, and offices have been required to fill the needs of the increasing Australian population. In addition, warehouses, factories, and wholesale distribution facilities have been required to further support this growth. In the tourism sector, there has been a need for more accommodation options in the major tourist destinations in the country.

Office space demand

In the office segment, the nation’s larger cities such as Melbourne and Sydney have remained competitive with some of the lowest vacancy rates in the world. In Sydney, the recent COVID-19 outbreak seemed to have led to a decline in office leasing enquiries, and therefore an increase in the vacancy rate in 2020. The same trend was seen in the prime office vacancy rate in Melbourne. It is yet to be seen if the office space demand will return to pre-pandemic levels in the near future.

This volume is consists of a paper entitled "The Transit Problems of Greater Sydney", presented by J.J.C. Bradfield to the Australian Town Planning Conference and Exhibition, held in Adelaide from 17-24 October 1917.

Bradfield advocated a transit scheme to improve transport in Sydney which included the electrification of railway lines and the construction of a bridge between Sydney and North Sydney.

The volume also contains copies of photographs, maps, plans and other illustrative material which Bradfield used in his presentation. There are 12 appendices related to population growth and distribution used to support his theory.

[At the time of the presentation, J.J.C. Bradfield was Chief Engineer, Metropolitan Railway Construction, NSW Government Railways and Tramways.]

Context

The water quality of Sydney's iconic beaches. The data is available at the New South Wales State Government Beachwatch website.

Sydney beaches were in the news this summer with high rainfall causing concerns about the safety of the water.

The dataset includes both water quality and historical weather data from 1991 until 2025.

Has the water quality declined over this period? How does rainfall impact E-coli bacteria levels? Are some swimming sites particularly prone to high bacteria levels following rain?

The Local Government Administration industry faced challenging conditions from 2019-20 to 2021-22 due to issues presented by the pandemic. Demand for ancillary services like gyms and swimming pools plummeted, hindering local governments' ability to generate revenue from user-based charges, like service fees and fines. Despite a recovery in demand since restrictions were lifted, local governments continue to face intense competition from private sector competitors. Inflation has constrained local governments' ability to significantly increase their revenue. The cost-of-living crisis has added another layer of consideration for local governments contemplating policy changes, as councillors try to avoid voter backlash at local council elections. The Victorian and NSW state governments have also enforced rate caps, limiting local authorities' power to increase household rates in line with high inflation. With industry revenue climbing, local governments have managed to expand their operating margins thanks to increased funding from upstream government grants and subsidies, as well as from outsourcing services, which has lowered wage costs. Revenue is expected to have increased at an annualised rate of 0.7% through the end of 2025-26, reaching $67.3 billion. However, this trend is anticipated to include a 0.6% drop in 2025-26. Improvements in Australian economic conditions, like easing interest rates, are forecast to foster revenue growth in the coming years. Rising economic activity and a growing population are poised to benefit local governments, as increased tax revenue for upstream government bodies places upwards pressure on funding and grants for local governments nationwide. While increased consumer spending and government funding promise higher revenue, local governments’ not-for-profit nature is likely to lead to higher capital expenditure, driving up depreciation costs and limiting growth in operating margins over the next five years. The number of local governments is projected to remain stable due to the absence of planned council amalgamations. However, population growth trends may dictate future council mergers or demergers. Overall, industry revenue is forecast to grow at an annualised 2.1% over the five years through 2030-31, to total $74.7 billion.

Water treatment services are closely tied to Australia's broader water security. Purification and wastewater management are crucial for maximising the use of existing resources and minimising environmental impact. The millennium drought in the 2000s still resonates today, as public and private sector funding continues to flow towards improving water security. An expanding population has ensured ongoing demand for water treatment, as more households require stable drinking water and sewage management services. However, in recent years, high annual rainfall has reduced demand for bulk water purification and the use of desalination plants. Together, these trends contributed to revenue declining at an annualised 1.0% over the past five years, including a 1.3% fall in 2025-26, to total an estimated $8.0 billion. The development of new housing relies on adequate water and sewerage treatment capacity, prompting large-scale investments in infrastructure programs. For example, Sydney Water’s $595.0 million North West Treatment Hub aims to support population growth in Sydney's north west region. Programs like this have increased fixed costs, and since operators have limited scope to raise prices, profit margins have declined slightly since 2020-21 amid subdued revenue growth. The updated Australian Drinking Water Guidelines, released in June 2025, lowered the acceptable PFAS concentrations, forcing utilities to update treatment systems, as seen in Sydney Water’s $3.5 million PFAS system at Cascade. Looking ahead, climate change and population growth will pressure water treatment providers to amplify existing resources and deal with stretched water availability. The water supply chain is preparing for the potential impacts of climate change and implementing mitigation strategies to ensure long-term water security. Over the coming years, the use of water treatment techniques that focus on recycling existing resources, like desalination and purified recycled water, will reinforce demand. These ventures will require a significant influx of capital investments, which will increase fixed costs in the industry. Higher capital costs will be passed on to consumers through higher bills. Overall, revenue is projected to grow at an annualised 1.2% over the next five years, and is forecast to reach $8.5 billion.
