I just read (in Alan Taylor's Book "American Colonies") that Australia and New Zealand weren't the only destinantions for convicts, seems like the British West Indies and the US of A were also used.
Of course we got the con artists in stead of sheep stealers.
Wasn't there a member of U-2 who was asked by the authorities upon arrival in Australia if he had ever been convicted of a felony. He replied; "I didn't know it was still a requirement."
