The first elements of the First Fleet carrying 736 convicts from Great Britain to Australia arrive at Botany Bay.

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.

Great Britain, also known as the Kingdom of Great Britain, was a sovereign state in Western Europe from 1707 to the end of 1800. The state was created by the 1706 Treaty of Union and ratified by the Acts of Union 1707, which united the Kingdom of England and the Kingdom of Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands, with the exception of the Isle of Man and the Channel Islands. The unitary state was governed by a single parliament at the Palace of Westminster, but distinct legal systems—English law and Scots law—remained in use, as did distinct educational systems and religious institutions, namely the Church of England and the Church of Scotland remaining as the national churches of England and Scotland respectively.

Botany Bay is an open oceanic embayment, located in Sydney, New South Wales, Australia, 13 km (8 mi) south of the Sydney central business district. Its source is the confluence of the Georges River at Taren Point and Sans Souci as well as the Cooks River at Kyeemagh, which flows 10 km (6 mi) to the east before meeting its mouth at the Tasman Sea, midpoint between the suburbs of La Perouse and Kurnell. The northern headland of the entrance to the bay from the Tasman Sea is Cape Banks, and, on the southern side, the outer headland is Cape Solander, and the inner headland is Sutherland Point.
