I can't tell if you are being serious,but in case you really don't know, the British Empire used to send its convicts to Australia, as it was a new colony and was in need of as many people as possible. So instead of putting those people in prison, they sent them off to Australia, without the ability to ever come back.

Starting in 1788, Britain used a policy of 'Transportation' to colonies in Australia to relieve overcrowding in its prisons at home. Of course, Australia is now an independent country. The book 'A Commonwealth of Thieves' by Thomas Keneally provides a very readable narrative of the first British people to settle there.
