Transportation to the american colonies had come to an end, therefore, an alternative place was needed to send convicted felons. Captain James Cook was sent out in 1770 to explore the area, and his reports and maps helped to raise interest in the concept of a penal colony in the Australian territories.
The British decision to establish a colony in Australia was ultimately driven by the need for a remote location to manage its growing prison population and gain control of the vast resources found there. The British sought to expand their territories and exploit Australia's natural resources, including its agricultural land and mineral deposits.
By colonising Australia, the British were able to establish control over the land, displace its indigenous population, and exploit the resources for their own economic benefit. Over time, the British established several colonies in Australia, and eventually formed the federation of Australia in 1901.
