Who did the english send to the settlements to increase population in australia

Convict's, free settlers and assisted immigrants.

Explanation:

Britain chose Australia as the site of a penal colony, and in 1787, the First Fleet of eleven convict ships set sail for Botany Bay, arriving on 20 January 1788 to found Sydney, New South Wales, the first European settlement on the continent.

Australia was settled by convicts, but today, locals are embracing their crime-ridden past. New South Wales, a state in southeast Australia, was founded by the British as a penal colony in 1788.

Between 1793 and 1850 nearly 200,000 free settlers and assisted immigrants chose to migrate to Australia to start a new life. The majority were English agricultural workers or domestic servants who outnumbered the Irish and Scottish migrants
