In some ways yes, it populated a new land and exported home grown problems.
The British put their prisoners there.
to create a place to send prisoners
a punishment for convicts as Britain had no where else to put them
Australia
Australia was colonised by British prisoners. The British government sent a fleet of convicts and officers, under the command of Captain Arthur Phillip, to colonise the land that James Cook had named and claimed as "New South Wales".
Australia was originally set up as a penal colony where Britain sent prisoners.
Prison hulks were old, decommissioned vessels moored in British harbours to house prisoners from what were then overcrowded gaols. Many prisoners awaiting transportation (as a punishment, often in lieu of the death penalty) to the colonies (usually Australia, especially after the War of Independence removed the American colonies from British control) we sent to the hulks before starting their journeys to the colonies on (hopefully) more seaworthy ships.
The British decided to settle in Australia in order to establish a penal colony and relieve overcrowding in British prisons. Additionally, the British saw an opportunity to expand their empire through colonization and trade in the region.
I assume the question relates to the deportation of prisoners from England to our penal colonies being established in Australia (and elsewhere)? The problem was simply to remove the prisoners somewhere else. In 1787, the 'First Fleet' departed from England, to establish the first British penal colony settlement in Australia.
Australia was originally established as a penal colony, or convict settlement. The first Europeans to permanently settle in the country were British prisoners, and the officers and marines who led and guarded them.
Before the American Revolutionary War, British prisoners were sold as indentured servants to work on American farms. While an individual could indenture himself for 7 years in exchange for passage across the ocean, a prisoner's indenture could last 30 years. During the Revolutionary War, prisoners made up the bulk of the British army. After that war, England needed a place to send prisoners. Australia was available. Prisoners were sent from jails in England to prisons in Australia. After the prisoners served their sentences, they were released from prison in Australia. They would never return to England. Their relatives in England would never hear from them again. It was as if once they walked on board the boat they went to their deaths. It was possible for a person in England to write to a person in Australia and get an answer. However, it required an address. Without knowing where they were, it was impossible to contact them. They were dead to their relatives back in England.
Australia was claimed by Great Britain and colonized by British prisoners. During the Civil War, Australia was still a remote outpost of Great Britain, with no appreciable effect on the war. Of the British colonies, Canada and Jamaica would have had much more of a bearing on the Civil War due to their proximity.
