A ticket of leave was a document of parole issued to convicts who had shown they could now be trusted with some freedoms. Originally the ticket was issued in Britain and later adapted by the United States, Canada and Ireland.
The ticket of leave system was first introduced by Governor Philip Gidley King in 1801. Its principal aim was to reduce the burden on the fledgling colonial government of providing food from the government's limited stores to the convicts who were being transported from the United Kingdom to New South Wales. Convicts who seemed able to support themselves were awarded a ticket of leave. Before too long, tickets began to be given as a reward for good behaviour, which permitted the holders to seek employment within a specified district, but not leave it without the permission of the government or the district's resident magistrate. Each change of employer or district was recorded on the ticket.
Originally the ticket of leave was given without any relation to the period of the sentence a convict had already served. Some "gentlemen convicts" were issued with tickets on their arrival in the colony. Starting in 1811, the need to first officiate some time in servitude was established, and in 1821 Governor Brisbane introduced regulations specifying the lengths of sentences that had to be served before a convict could be considered for a ticket: four years for a seven-year sentence, six to eight years for a 14-year sentence, and 10 to 12 years for those with a life sentence. Once the full original sentence had been served, a "certificate of freedom" would be issued upon application.
