Oceania (UK: /ˌoʊsiˈɑːniə, ˌoʊʃi-, -ˈeɪn-/ OH-s(h)ee-AH-nee-ə, -⁠AY-, US: /ˌoʊʃiˈæniə, -ˈɑːn-/ OH-shee-A(H)N-ee-ə) is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Outside of the English-speaking world, Oceania is generally considered a continent, while Mainland Australia is regarded as its continental landmass. Spanning the Eastern and Western hemispheres, at the centre of the water hemisphere, Oceania is estimated to have a land area of about 9,000,000 square kilometres (3,500,000 sq mi) and a population of around 46.3 million as of 2024. Oceania is the smallest continent in land area and the second-least populated after Antarctica.

Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia, French Polynesia, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much less developed economies of Kiribati, Papua New Guinea, Tuvalu, Vanuatu, and Western New Guinea. The largest and most populous country in Oceania is Australia, and the largest city is Sydney. Puncak Jaya in Indonesia is the highest peak in Oceania at 4,884 m (16,024 ft).

Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.

Sources of water pollution are either point sources or non-point sources. Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant, or an oil spill. Non-point sources are more diffuse. An example is agricultural runoff. Pollution is the result of the cumulative effect over time. Pollution may take many forms. One would is toxic substances such as oil, metals, plastics, pesticides, persistent organic pollutants, and industrial waste products. Another is stressful conditions such as changes of pH, hypoxia or anoxia, increased temperatures, excessive turbidity, or changes of salinity). The introduction of pathogenic organisms is another. Contaminants may include organic and inorganic substances. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers.

There are eight capital cities in Australia, each of which functions as the seat of government for the state or territory in which it is located. One of these, Canberra, is also the national capital. Section 125 of the Constitution of Australia specified that the seat of the national government, that is, the national capital, would be in its own territory within New South Wales, at least 100 miles (161 km) from Sydney. The Constitution specified that until this national capital was ready, the Parliament would sit in Melbourne. In 1927, the national capital was finally ready and the national government relocated from its former seat in Melbourne to Canberra within the Australian Capital Territory (or the Federal Capital Territory as it was known at the time).

In each state and internal territory, the capital is also the jurisdiction's most populous city. The Australian external territory of Norfolk Island has its official capital at Kingston, although this acts merely as the administrative centre of government; its de facto capital is Burnt Pine.

The 1956 Summer Olympics, officially the Games of the XVI Olympiad and officially branded as Melbourne 1956, were an international multi-sport event held in Melbourne, Victoria, Australia, from 22 November to 8 December 1956, with the exception of the equestrian events, which were held in Stockholm, Sweden, in June 1956.

These Games were the first to be staged in the Southern Hemisphere and Oceania, as well as the first to be held outside Europe and North America. Melbourne is the most southerly city ever to host the Olympics. Due to the Southern Hemisphere's seasons being different from those in the Northern Hemisphere, the 1956 Games did not take place at the usual time of year, because of the need to hold the events during the warmer weather of the host's spring/summer (which corresponds to the Northern Hemisphere's autumn/winter), resulting in the only summer games ever to be held in November and December. Australia hosted the Games for a second time in 2000 in Sydney, New South Wales, and will host them again in 2032 in Brisbane, Queensland.

The 2000 Summer Olympics, officially the Games of the XXVII Olympiad, officially branded as Sydney 2000, and also known as the Games of the New Millennium, were an international multi-sport event held from 15 September to 1 October 2000 in Sydney, New South Wales, Australia. It marked the second time the Summer Olympics were held in Australia, and in the Southern Hemisphere, the first being in Melbourne, in 1956.

Teams from 199 countries participated in the 2000 Games, which were the first to feature at least 300 events in its official sports program. The Games were estimated to have cost A$6.6 billion. These were the final Olympic Games under the IOC presidency of Juan Antonio Samaranch before the arrival of his successor Jacques Rogge.

A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact.

The word quarry can also include the underground quarrying for stone, such as Bath stone.

Brisbane (/ˈbrɪzbən/ BRIZ-bən; Turrbal/Yagara: Meanjin, Meaanjin, Maganjin or Magandjin) is the capital and largest city of the state of Queensland and the third-most populous city in Australia, with a population of approximately 2.8 million. Brisbane lies at the centre of South East Queensland and is located roughly in the midpoint of Australia's eastern coastline. It is an urban agglomeration with a population of over 4 million. The central business district is situated within a peninsula of the Brisbane River about 15 km (9 mi) from its mouth at Moreton Bay. Greater Brisbane sprawls over the hilly floodplain of the Brisbane River Valley between Pacific Ocean and the Taylor and D'Aguilar mountain ranges, encompassing several local government areas, most centrally the City of Brisbane, the most populous local government area in Australia. The demonym of Brisbane is Brisbanite or Brisbaner.

The Moreton Bay penal settlement was founded in 1824 at Redcliffe as a place for secondary offenders from the Sydney colony, but in May 1825 moved to North Quay on the banks of the Brisbane River, so named for the Governor of New South Wales Sir Thomas Brisbane. German Lutherans established the first free settlement of Zion Hill at Nundah in 1838, and in 1859 Brisbane was chosen as Queensland's capital when the state separated from New South Wales. During World War II, the Allied command in the South West Pacific was based in the city, along with the headquarters for General Douglas MacArthur of the United States Army.

The eastern states of Australia are the states adjoining the east continental coastline of Australia. These are the mainland states of Victoria, New South Wales and Queensland, and the island state of Tasmania. The Australian Capital Territory and Jervis Bay Territory, while not states, are also included. On some occasions, the southern state of South Australia is also included in this grouping due to its economic ties with the eastern states.

Regardless of which definition is used, the eastern states include the great majority of the Australian population. They contain the federal capital Canberra and Australia's three largest cities Sydney, Melbourne and Brisbane (all capitals of the respective east coast states). Of the 19 Australian cities with populations over 100,000 in 2021, 16 were located in the eastern states under the restricted definition (17 if including South Australia), which includes the two non-capital cities with a population over 500,000: Gold Coast, Queensland and Newcastle, New South Wales. In terms of climate, the area is dominated by a humid subtropical zone, with some tropical (Queensland) and oceanic climate (Australian Capital Territory, Victoria, New South Wales) zones. In most situations, the eastern states are defined as those who use Australian Eastern Standard Time (AEST), and that is the definition that this article will adhere to, unless noted.

New South Wales (commonly abbreviated as NSW) is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. Its coast borders the Coral and Tasman Seas to the east. The Australian Capital Territory and Jervis Bay Territory are enclaves within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. In December 2024, the population of New South Wales was over 8.5 million, making it Australia's most populous state. Almost two-thirds of the state's population, 5.3 million, live in the Greater Sydney area.

The Colony of New South Wales was founded as a British penal colony in 1788. It originally comprised more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825. The colony then also included the island territories of Van Diemen's Land, Lord Howe Island, and Norfolk Island. During the 19th century, most of the colony's area was detached to form separate British colonies that eventually became the various states and territories of Australia. The Swan River Colony (later called the Colony of Western Australia) was never administered as part of New South Wales.

The Australian Capital Territory (ACT), known as the Federal Capital Territory until 1938, is an internal territory of Australia. Canberra, the capital city of Australia, is situated within the territory, and is the territory's primate city. It is located in southeastern Australian mainland as an enclave surrounded by the state of New South Wales (NSW). Exclaved from NSW after federation as the seat of government for the new nation, the territory hosts parliament house, High Court of Australia and the head offices of many Australian Government agencies.

On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least 100 miles (160 km) from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the Seat of Government Act 1908 was passed in 1908 which specified a capital in the Yass-Canberra region. The territory was transferred to the federal government by New South Wales in 1911, two years prior to the capital city being founded and formally named as Canberra in 1913.

A fish pond or fishpond is a controlled pond, small artificial lake or retention basin that is stocked with fish and is used in aquaculture for fish farming, for recreational fishing, or for ornamental purposes.

Fish ponds are a classical garden feature in East Asian residence, such as the Classical Gardens of Suzhou of China, the Imperial Palace of Japan and the Gyeongbokgung Palace of South Korea. In Medieval Europe, it was also typical for monasteries and castles (small, partly self-sufficient communities) to have a fish pond.

The 2002 Commonwealth Games, officially known as the XVII Commonwealth Games and commonly known as Manchester 2002, were an international multi-sport event for the members of the Commonwealth held in Manchester, England, from 25 July to 4 August 2002. According to planning, this event was to be held in a country in the United Kingdom as part of the Golden Jubilee of Elizabeth II, head of the Commonwealth. England was the only bidder for the event and, in an internal process, Manchester was selected for the 2002 Games ahead of London. The Manchester bid used projects which were part of the failed bid for the 2000 Summer Olympics and Paralympics, which were awarded to Sydney, Australia. The 2002 Commonwealth Games was, prior to the 2012 Summer Olympics, the largest multi-sport event ever to be held in the UK, eclipsing the London 1948 Summer Olympics in terms of teams and athletes participating. The 2002 Commonwealth Games had the largest number of events of any Commonwealth Games in history, featuring 281 events across 17 sports.

The event was considered a success for the host city, providing an opportunity to display how Manchester reeinvented itself as city, following the 1996 IRA bombing. The Games formed the main catalyst for the widespread regeneration and heavy development of Manchester and bolstered its reputation as a European and global city internationally. Rapid economic development and continued urban regeneration of the now post-industrial Manchester continued after the Games, which helped cement its place as one of the principal cultural cities in the United Kingdom.

Circular Quay is a harbour, former working port and now international passenger shipping terminal, public piazza and tourism precinct, heritage area, and transport node located in Sydney, New South Wales, Australia, on the northern edge of the Sydney central business district on Sydney Cove, between Bennelong Point and The Rocks. It is part of the local government area of the City of Sydney.

The Circular Quay area is a popular neighbourhood for tourism and consists of walkways, pedestrian malls, parks and restaurants. It hosts a number of ferry wharves, bus stops, and a railway station. Often referred to as the "gateway to Sydney", the precinct has views of the Sydney Harbour Bridge and the Sydney Opera House and is a common location for viewing Sydney New Year's Eve fireworks.

Section 125 of the Constitution of Australia deals with matters relating to the seat of the Commonwealth government. It specifies that it will be in its own territory that is under direct Commonwealth control, that will be at least 100 miles (160 km) from Sydney and will have an area of no less than 100 square miles (260 km). It also specifies the temporary seat of government to be Melbourne, which was to be used until the permanent seat of government was built.

Its precise text is:

Melbourne is the capital and most populous city of the Australian state of Victoria, and the second most-populous city in Australia, after Sydney. The city's name generally refers to a 2,453 km (947 sq mi) area, comprising an urban agglomeration of 31 local government areas. The name is also used to specifically refer to the local government area named City of Melbourne, whose area is centred on the Melbourne central business district and some immediate surrounds.

The city occupies much of the northern and eastern coastlines of Port Phillip Bay. As of 2024, the population of the city was 5.35 million, or 19% of the population of Australia; inhabitants are known as "Melburnians".

Kingston (Norf'k: Daun a'Taun) is the capital and main administrative centre of the Australian external territory of Norfolk Island. The Norfolk Island Regional Council is based in Kingston. The settlement is the second-oldest in Australia, having been founded a little over a month after Sydney. It is part of the Kingston and Arthur's Vale Historic Area World Heritage Site.

The history of Australia from 1788 to 1850 covers the early British colonial period of Australia's history. This started with the arrival in 1788 of the First Fleet of British ships at Port Jackson on the lands of the Eora, and the establishment of the penal colony of New South Wales as part of the British Empire. It further covers the European scientific exploration of the continent and the establishment of the other Australian colonies that make up the modern states of Australia.

After several years of privation, the penal colony gradually expanded and developed an economy based on farming, fishing, whaling, trade with incoming ships, and construction using convict labour. By 1820, however, British settlement was largely confined to a 100-kilometre (62 mi) radius around Sydney and to the central plain of Van Diemen's land. From 1816, penal transportation to Australia increased rapidly and the number of free settlers grew steadily. Van Diemen's Land became a separate colony in 1825, and free settlements were established at the Swan River Colony in Western Australia (1829), the Province of South Australia (1836), and in the Port Philip District (1836). The grazing of cattle and sheep expanded inland, leading to increasing conflict with Aboriginal people on their traditional lands.

Vere Gordon Childe (14 April 1892 – 19 October 1957) was an Australian archaeologist who specialised in the study of European prehistory. He spent most of his life in the United Kingdom, working as an academic for the University of Edinburgh and then the Institute of Archaeology, London. He wrote twenty-six books during his career. Initially an early proponent of culture-historical archaeology, he later became the first exponent of Marxist archaeology in the Western world.

Born in Sydney to a middle-class English migrant family, Childe studied classics at the University of Sydney before moving to England to study classical archaeology at the University of Oxford. There, he embraced the socialist movement and campaigned against the First World War, viewing it as a conflict waged by competing imperialists to the detriment of Europe's working class. Returning to Australia in 1917, he was prevented from working in academia because of his socialist activism. Instead, he worked for the Labor Party as the private secretary of the politician John Storey. Growing critical of Labor, he wrote an analysis of their policies and joined the radical labour organisation Industrial Workers of the World. Emigrating to London in 1921, he became librarian of the Royal Anthropological Institute and journeyed across Europe to pursue his research into the continent's prehistory, publishing his findings in academic papers and books. In doing so, he introduced the continental European concept of an archaeological culture—the idea that a recurring assemblage of artefacts demarcates a distinct cultural group—to the British archaeological community.

Yellow-eye mullet (Aldrichetta forsteri), also known as Coorong mullet (after the Coorong area of South Australia), conmuri, estuary mullet, Forster's mullet, freshwater mullet, pilch, pilchard, Victor Harbor mullet, yelloweye and yellow-eyed mullet, are small, near-shore fish found in temperate waters of southern Australia from just north of Sydney, New South Wales to Shark Bay in Western Australia, around Tasmania, and New Zealand.
