The modern Greater Sydney area covers the traditional lands of 28 known Aboriginal clans.


History


First inhabitants of the region

The first people to inhabit the area now known as Sydney were Aboriginal Australians who had migrated from northern Australia and before that from southeast Asia. Flaked pebbles found in Western Sydney's gravel sediments might indicate human occupation from 45,000 to 50,000 years BP, while

has shown evidence of human activity in the Sydney region from around 30,000 years ago. Prior to the arrival of the British, there were 4,000 to 8,000 Aboriginal people in the greater Sydney region. The inhabitants subsisted on fishing, hunting, and gathering plant foods and shellfish. The diet of the coastal clans was more reliant on

whereas the food of hinterland clans was more focused on forest animals and plants. The clans had distinctive sets of equipment and weapons mostly made of stone, wood, plant materials, bone and shell. They also differed in their body decorations, hairstyles, songs and dances. Aboriginal clans had a rich ceremonial life which was part of a belief system centering on ancestral, totemic and supernatural beings. People from different clans and language groups came together to participate in initiation and other ceremonies. These occasions fostered trade, marriages and clan alliances.Attenbrow (2010). pp. 28,158 The earliest British settlers recorded the word '

' as an Aboriginal term meaning either 'people' or 'from this place'. The clans of the Sydney area occupied land with traditional boundaries. There is debate, however, about which group or nation these clans belonged to, and the extent of differences in language, dialect and initiation rites. The major groups were the coastal Eora people, the Dharug (Darug) occupying the inland area from Parramatta to the Blue Mountains, and the Dharawal people south of Botany Bay. Darginung and Gundungurra languages were spoken on the fringes of the Sydney area.Attenbrow (2010). pp. 22-29 The first meeting between Aboriginals and British explorers occurred on 29 April 1770 when Lieutenant James Cook landed at Botany Bay (Kamay) and encountered the Gweagal clan. Two Gweagal men opposed the landing party and in the confrontation one of them was shot and wounded. Cook and his crew stayed at Botany Bay for a week, collecting water, timber, fodder and botanical specimens and exploring the surrounding area. Cook sought to establish relations with the Aboriginal population without success.


Convict town (1788–1840)

Britain had been sending convicts to its American colonies for most of the eighteenth century, and the loss of these colonies in 1783 was the impetus for the decision to establish a penal colony at Botany Bay. Proponents of colonisation also pointed to the strategic importance of a new base in the Asia-Pacific region and its potential to provide much-needed timber and flax for the navy. The

Sydney Cove offered a fresh water supply and a safe harbour, which Philip described as being, 'with out exception the finest Harbour in the World ..Here a Thousand Sail of the Line may ride in the most perfect Security'. The settlement was planned to be a self-sufficient penal colony based on subsistence agriculture. Trade and ship building were banned in order to keep the convicts isolated. However, the soil around the settlement proved poor and the first crops failed, leading to several years hunger and strict food rationing. The food crisis was relieved with the arrival of the

on the Cumberland Plain. By 1804, the colony was self-sufficient in food. A smallpox epidemic in April 1789 killed about half the Indigenous population of the Sydney region. In November 1790 Bennelong led a group of survivors of the Sydney clans into the settlement, establishing a continuous presence of Aboriginal Australians in settled Sydney. Phillip had been given no instructions for urban development, but in July 1788 submitted a plan for the new town at

. It included a wide central avenue, a permanent Government House, law courts, hospital and other public buildings, but no provision for warehouses, shops, or other commercial buildings. Phillip promptly ignored his own plan, and unplanned development became a feature of Sydney's topography.After the departure of Phillip in December 1792, the colony's military officers began acquiring land and importing consumer goods obtained from visiting ships. Former convicts also engaged in trade and opened small businesses. Soldiers and former convicts built houses on Crown land, with or without official permission, in what was now commonly called Sydney town. Governor William Bligh (180608) imposed restrictions on trade and commerce in the town and ordered the demolition of buildings erected on Crown land, including some owned by past and serving military officers. The resulting conflict culminated in the Rum Rebellion of 1808, in which Bligh was deposed by the New South Wales Corps. Governor

(18101821), played a leading role in the development of Sydney and New South Wales, establishing a bank, a currency and a hospital. He employed a planner to design the street layout of Sydney and commissioned the construction of roads, wharves, churches, and public buildings. Parramatta Road, linking Sydney and Parramatta, was opened in 1811 and a road across the Blue Mountains was completed in 1815, opening the way for large scale farming and grazing in the lightly-wooded pastures west of the

. Following the departure of Macquarie, official policy encouraged the emigration of free British settlers to New South Wales. Immigration to the colony increased from 900 free settlers in 1826-30 to 29,000 in 1836-40, many of whom settled in Sydney. By the 1840s Sydney exhibited a geographic divide between poor and working class residents living west of the Tank Stream in areas such as The Rocks, and the more affluent residents living to its east. Free settlers, free-born residents and former convicts now represented the vast majority of the population of Sydney, leading to increasing public agitation for responsible government and an end to transportation. Transportation to New South Wales ceased in 1840.

, an attempt to march on Sydney, commandeer a ship, and sail to freedom. Poorly armed, and with their leader Philip Cunningham captured, the main body of insurgents were routed by about 100 troops and volunteers at Rouse Hill. At least 39 convicts were killed in the uprising and subsequent executions. As the colony spread to the more fertile lands around the Hawkesbury river, north-west of Sydney, conflict between the settlers and the Darug people intensified, reaching a peak from 1794 to 1810. Bands of Darug people, led by Pemulwuy and later by his son Tedbury, burned crops, killed livestock and raided settler huts and stores in a pattern of resistance that was to be repeated as the colonial frontier expanded. A military garrison was established on the Hawkesbury in 1795. The death toll from 1794 to 1800 was 26 settlers and up to 200 Darug. Conflict again erupted from 1814 to 1816 with the expansion of the colony into Dharawal country in the Nepean region south-west of Sydney. Following the deaths of several settlers, Governor Macquarie despatched three military detachments into Dharawal lands, culminating in the Appin massacre (April 1816) in which at least 14 Aboriginal people were killed.


Colonial city (1841–1900)

The New South Wales Legislative Council was transformed into a semi-elected body in 1842. The town of Sydney was declared a city the same year, and a governing council established, elected on a restrictive property franchise.The discovery of gold in New South Wales and Victoria in 1851 initially caused some economic disruption as male workers moved to the goldfields. Melbourne soon overtook Sydney as Australia's largest city, leading to an enduring rivalry between the two cities. However, increased immigration from overseas and wealth from gold exports increased demand for housing, consumer goods, services and urban amenities.Goodman, David (2013). "The gold rushes of the 1850s". ''The Cambridge History of Australia, Volume I''. pp. 180–81. The New South Wales government also stimulated growth by investing heavily in railways, trams, roads, ports, telegraph, schools and urban services. The population of Sydney and its suburbs grew from 95,600 in 1861 to 386,900 in 1891. The city developed many of its characteristic features. The growing population packed into rows of terrace houses in narrow streets. New public buildings of sandstone abounded, including at the University of Sydney (1854–61), the Australian Museum (1858–66), the Town Hall (1868–88), and the
General Post Office The General Post Office (GPO) was the state postal system and telecommunications carrier of the United Kingdom until 1969. Before the Acts of Union 1707, it was the postal system of the Kingdom of England, established by Charles II in 1660. ...
(1866–92). Elaborate coffee palaces and hotels were erected. Exotic plants such as jacarandas and frangipani were introduced in parks and gardens. Daylight bathing at Sydney's beaches was banned, but segregated bathing at designated ocean baths was popular. Drought, the winding down of public works and a financial crisis led to economic depression in Sydney throughout most of the 1890s. Meanwhile, the Sydney-based premier of New South Wales, George Reid, became a key figure in the process of federation.

in 1900 prompted the new state government to modernise the wharves and demolish inner-city slums. The outbreak of the First World War in 1914 saw more Sydney males volunteer for the armed forces than the Commonwealth authorities could process, and helped reduce unemployment in the city. Those returning from the war in 1918 were promised "homes fit for heroes" in new suburbs such as Daceyville and Matraville. "Garden suburbs" and mixed industrial and residential developments also grew along the rail and tram corridors. The population reached one million in 1926, after Sydney had regained its position as the most populous city in Australia. The government created jobs with massive public projects such as the electrification of the Sydney rail network and building the Sydney Harbour Bridge. Sydney was more severely affected by the

of the 1930s than regional NSW or Melbourne. New building almost came to a standstill, and by 1933 the unemployment rate for male workers was 28 per cent, but over 40 per cent in working class areas such as Alexandria and Redfern. Many families were evicted from their homes and shanty towns grew along coastal Sydney and Botany Bay, the largest being "Happy Valley" at La Perouse. The Depression also exacerbated political divisions. In March 1932, when populist Labor premier Jack Lang attempted to open the Sydney Harbour Bridge he was upstaged by

of the far-right New Guard, who slashed the ribbon with a sabre. In January 1938, Sydney celebrated the Empire Games and the sesquicentenary of European settlement in Australia. One journalist wrote, "Golden beaches. Sun tanned men and maidens...Red-roofed villas terraced above the blue waters of the harbour...Even Melbourne seems like some grey and stately city of Northern Europe compared with Sydney's sub-tropical splendours." Meanwhile, a congress of the "Aborigines of Australia", declared 26 January "A Day of Mourning" for "the whiteman's seizure of our country." With the outbreak of war in 1939, Sydney experienced a surge in industrial development to meet the needs of a wartime economy. Unemployment virtually disappeared and women moved into jobs previously male preserves. Sydney was attacked by Japanese submarines in May and June 1942 with 21 lives lost. Households throughout the city built air raid shelters and performed drills. A post-war immigration and baby boom saw a rapid increase in Sydney's population and the spread of low-density housing in suburbs throughout the Cumberland Plain. Immigrantsmostly from Britain and continental Europeand their children accounted for over three-quarters of Sydney's population growth between 1947 and 1971. The newly created Cumberland County Council oversighted low-density residential developments, the largest at Green Valley and Mount Druitt. Older residential centres such as Parramatta, Bankstown and Liverpool became suburbs of the metropolis. Manufacturing, protected by high tariffs, employed over a third of the workforce from 1945 to the 1960s. However, as the long post-war economic boom progressed, retail and other service industries became the main source of new jobs. An estimated one million onlookers, most of the city's population, watched as

landed in 1954 at Farm Cove where Captain Phillip had raised the Union Jack 165 years earlier, commencing her Australian Royal Tour. It was the first time a reigning monarch stepped onto Australian soil. Increasing high rise development in Sydney and the expansion of suburbs beyond the "green belt" envisaged by the planners of the 1950s resulted in community protests. In the early 1970s, trade unions and resident action groups imposed green bans on development projects in historic areas such as The Rocks. Federal, State and local governments subsequently introduced a range of heritage and environmental legislation. The Sydney Opera House was also controversial for its cost and disputes between architect Jørn Utzon and government officials. However, soon after it opened in 1973 it became a major tourist attraction and symbol of the city. The progressive reduction in tariff protection from 1974 began the transformation of Sydney from a manufacturing centre focused on the domestic market to a "world city" providing financial, commercial, cultural and educational services to local residents and Australian and overseas markets. From the 1980s, overseas immigration to Sydney grew rapidly, with Asia, the Middle East and Africa becoming major sources of immigrants. By 2021, the population of Sydney was over 5.2 million, with 40% of the population born overseas. China and India overtook England as the largest source countries for overseas-born residents.

play an important role in determining Sydney's weather patterns: drought and bushfire on the one hand, and storms and flooding on the other, associated with the opposite phases of the oscillation in Australia. The weather is moderated by proximity to the ocean, and more extreme temperatures are recorded in the inland western suburbs. At Sydney's primary weather station at Observatory Hill, extreme temperatures have ranged from on 18 January 2013 to on 22 June 1932. An average of 14.9 days a year have temperatures at or above in the central business district (CBD). In contrast, the metropolitan area averages between 35 and 65 days, depending on the suburb. The hottest day in the Sydney metropolitan area occurred in Penrith on 4 January 2020, where a high of was recorded. The average annual temperature of the sea ranges from in September to in February.

Sydney experiences an urban heat island effect. This makes certain parts of the city more vulnerable to extreme heat, including coastal suburbs. In late spring and summer, temperatures over are not uncommon, though hot, dry conditions are usually ended by a southerly buster, a powerful southerly that brings gale winds and a rapid fall in temperature.

) shift towards southeastern Australia, where they may damage homes and affect flights, in addition to making the temperature seem colder than it actually is. Rainfall has a moderate to low variability and has historically been fairly uniform throughout the year, although in recent years it has been more summer-dominant and erratic. Precipitation is usually higher in late summer through to early winter and lower in late winter to early spring. In late autumn and winter, east coast lows may bring large amounts of rainfall, especially in the CBD. In the warm season black nor'easters are usually the cause of heavy rain events, though other forms of low-pressure areas, including remnants of ex-cyclones, may also bring heavy deluge and afternoon thunderstorms, particularly in the western suburbs.

Suburbs surrounding the CBD include Woolloomooloo and Potts Point to the east, Surry Hills and Darlinghurst to the south, Pyrmont and Ultimo to the west, and Millers Point and The Rocks to the north. Most of these suburbs measure less than in area. The Sydney CBD is characterised by considerably narrow streets and thoroughfares, created in its convict beginnings in the 18th century. Several localities, distinct from suburbs, exist throughout Sydney's inner reaches.

Westfield Sydney, located beneath the Sydney Tower, is the largest shopping centre by area in Sydney. There is a long trend of gentrification amongst Sydney's inner suburbs. Pyrmont located on the harbour was redeveloped from a centre of shipping and international trade to an area of high density housing, tourist accommodation, and gambling.

The enforced rehousing of local residents due to the Millers Point/Barangaroo development has caused significant controversy despite the $6 billion worth of economic activity it is expected to generate. The suburb of Paddington is a well known suburb for its streets of restored terrace houses, Victoria Barracks, and shopping including the weekly Oxford Street markets.

, and City of Canada Bay. These span up to about 11 km west of the CBD. Suburbs in the Inner West have historically housed working class industrial workers, but have undergone gentrification over the 20th century. The region now mainly features medium- and high-density housing. Major features in the area include the University of Sydney and the Parramatta River, as well as a large cosmopolitan community and the nightlife hub on King Street in Newtown. The Anzac Bridge spans Johnstons Bay and connects Rozelle to Pyrmont and the city, forming part of the Western Distributor. The area is serviced by the T1, T2, and T3 railway lines, including the Main Suburban Line; which is the first to be constructed in New South Wales.
