Why do the British refer to First Fleet as colonisers?

The term "colonisers" is used to refer to the individuals who were part of the First Fleet, which was the first fleet of ships to arrive in Australia from Britain in 1788. The purpose of the First Fleet was to establish a penal colony in New South Wales, which is now part of Australia. The term "colonisers" is used because the First Fleet was the beginning of the British colonisation of Australia, which involved the establishment of British settlements and the displacement of the Indigenous Australian people.
