After arriving at Botany Bay on 18 January 1788, Governor Arthur Phillip judged the site poor for fresh water and farming. On 26 January 1788, the fleet moved into Port Jackson and anchored at Warrane/Sydney Cove, beginning a permanent British settlement in Australia.
In early February 1788, Phillip and his officials formally established British civil authority over the new settlement by proclaiming the colony of New South Wales. This proclamation turned a landing site into a colonial government, setting the legal framework for land claims, courts, and administration.
In 1790, the New South Wales Corps began arriving to replace the marines who had come with the First Fleet. Over time, its officers gained land and influence and became deeply involved in trade, helping create a powerful military-commercial elite in the colony.
In June 1790, the Second Fleet arrived with convicts and supplies, but it became notorious for extreme overcrowding and neglect at sea. Large numbers arrived sick or dying, increasing pressure on food and medical care and pushing the young colony closer to famine.
On 26 January 1808, officers of the New South Wales Corps arrested Governor William Bligh and took control of the colony’s administration. The coup reflected long-running conflicts over land, trade (including rum used as a form of currency), and who would control government power in New South Wales.
Lachlan Macquarie assumed office as governor on 1 January 1810, ending the period of military dominance after the Rum Rebellion. He expanded public works, strengthened administration, and promoted plans that helped turn the penal settlement into a more complex colonial society.
On 3 December 1825, Van Diemen’s Land (later Tasmania) was separated from New South Wales and made its own colony. This reflected growing settlement beyond Sydney and the British need to manage distant penal and free communities with distinct administrations.
By the late 1820s, conflict in Tasmania (then Van Diemen’s Land) intensified between settlers and Aboriginal Tasmanians as settlement expanded onto Indigenous land. The violence, often called the Black War, showed how colonization could become sustained frontier warfare with devastating consequences for Indigenous communities.
On 28 December 1836, Governor John Hindmarsh read a proclamation that established the first government of the Province of South Australia at Holdfast Bay (Glenelg). The event publicly marked the start of local colonial administration for a planned, “free” colony, distinct from earlier penal beginnings in New South Wales.
On 10 June 1838, at least 28 Aboriginal people were killed at Myall Creek in New South Wales. Unlike most frontier killings, the case led to trials and the execution of several perpetrators, becoming a notable (and contested) moment in how colonial courts handled violence against Indigenous people.
In 1840, Britain ended the transportation of convicts to New South Wales. The change signaled a shift in how the colony was expected to grow—less as a prison outpost and more as a settler society with a larger free population and expanding local institutions.
On 1 July 1851, the Port Phillip District was separated from New South Wales and became the Colony of Victoria. This administrative split recognized rapid population growth and economic change in the south, and it accelerated the pattern of distinct colonies developing their own politics and priorities.
On 24 October 1889, New South Wales Premier Henry Parkes called for the Australian colonies to federate, arguing for shared national government on issues like defense. The speech mattered because it moved federation from a largely political idea into a wider public campaign.
From 2 March to 9 April 1891, delegates met in Sydney at a national convention to design a federal system and produce an early constitution draft. Although federation did not happen immediately, the 1891 draft became a key blueprint for the conventions and referendums that followed in the late 1890s.
Between 1898 and 1900, the colonies held referendums on a proposed federal constitution. Early votes revealed disagreements and required changes, but later referendums produced enough public support to move the plan forward to the British Parliament.
On 9 July 1900, Queen Victoria gave Royal Assent to the Commonwealth of Australia Constitution Act, after it passed the British Parliament. This law provided the legal basis for uniting the self-governing colonies into a federal Commonwealth and set the start date for the new nation.
On 1 January 1901, the Commonwealth of Australia was inaugurated in Sydney, with the proclamation and the swearing-in of the first Governor-General and the first federal ministry. Federation turned six British colonies into one nation-state with a federal constitution, while the former colonies became states with their own parliaments.
