The British First Fleet, led by Arthur Phillip, sails into Port Jackson (Sydney Harbour) to establish Sydney, the first permanent European settlement on Australia. Commemorated as Australia Day.

The First Fleet were eleven British ships which transported a group of settlers to mainland Australia, marking the beginning of the European colonisation of Australia. It consisted of two Royal Navy vessels, three storeships and six convict transports under the command of Captain Arthur Phillip. On 13 May 1787, the ships, with over 1,400 convicts, marines, sailors, colonial officials and free settlers onboard, left Portsmouth and travelled over 24,000 kilometres (15,000 mi) and over 250 days before arriving in Botany Bay on 18 January 1788. Governor Arthur Phillip rejected Botany Bay choosing instead Port Jackson, to the north, as the site for the new colony; they arrived there on 26 January 1788, establishing the colony of New South Wales, as a penal colony which would become the first British settlement in Australia.

Arthur Phillip was a British Royal Navy officer who served as the first governor of the Colony of New South Wales.

Port Jackson, commonly known as Sydney Harbour, is a natural harbour on the east coast of Australia, around which Sydney was built. It consists of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers. The harbour is an inlet of the Tasman Sea. It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney.

Sydney is the capital city of the state of New South Wales and the most populous city in Australia. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about 80 km (50 mi) from the Pacific Ocean in the east to the Blue Mountains in the west, and about 80 km (50 mi) from Ku-ring-gai Chase National Park and the Hawkesbury River in the north and north-west, to the Royal National Park and Macarthur in the south and south-west. Greater Sydney consists of 658 suburbs, spread across 33 local government areas. Residents of the city are colloquially known as "Sydneysiders". The estimated population in June 2024 was 5,557,233, which is about 66% of the state's population. The city's nicknames include the Emerald City and the Harbour City.
