Context: The Incredible Journey of Mary Bryant is a 2005 miniseries loosely based on the life of Mary Bryant, an English girl from Cornwall convicted of petty theft who was transported to the Australian Penal Colony on the First Fleet with other prisoners bound for Botany Bay.  It is written by Peter Berry and directed by Peter Andrikidis.  The film had a budget in excess of 15 million, making it the largest-budget television mini-series produced in Australia. Mary Bryant (1765–after 1794) was a Cornish convict sent to Australia.  She became one of the first successful escapees from the fledgling Australian penal colony. The Macquarie Harbour Penal Station, a former British colonial penal settlement, established on Sarah Island, Macquarie Harbour, in the former colony of Van Diemen's Land, now Tasmania, operated between 1822 and 1833.  The settlement housed mainly male convicts, with a small number of women.  During its 11 years of operation, the penal colony achieved a reputation as one of the harshest penal settlements in the Australian colonies.  The formal penal station is located on the 8 ha Sarah Island that now operates as an historic site under the direction of the Tasmania Parks and Wildlife Service. Solomon Blay (20 January 1816 – 20 August 1897) was an English convict transported to the Australian penal colony of Van Diemen's Land (present-day Tasmania).  Once his sentence was served, he gained notoriety as a hangman in Hobart, and is believed to have hanged over 200 people in the course of a long career spanning from 1840 to 1891.  This made him the longest serving hangman in the British Empire. Between 1842 and 1849, 234 juvenile offenders were transported to Western Australia on seven convict ships, even though the colony was not then classed as a penal colony.  From 1850 to 1868, Western Australia was a full-fledged penal colony, and during that time over 9,000 convicts were transported to the colony on 43 convict ship voyages. Robert Watson (1756–1819) was a British sailor who arrived in Australia with the First Fleet as quartermaster of "Sirius" . The First Fleet is the name given to the 11 ships that left England on 13 May 1787 to found the penal colony that became the first European settlement in Australia.  The Fleet consisted of two Royal Navy vessels, three store ships and six convict transports, carrying between 1,000 and 1,500 convicts, marines, seamen, civil officers and free people (accounts differ on the numbers), and a vast quantity of stores.  From England, the Fleet sailed southwest to Rio de Janeiro, then east to Cape Town and via the Great Southern Ocean to Botany Bay, arriving over the period of 18 to 20 January 1788, taking 250 to 252 days from departure to final arrival. The Outlaw Michael Howe is a 2013 Australian historical drama film written and directed by Brendan Cowell.  Set in the early 19th century, the film is based on the exploits of Michael Howe, an Englishman who was transported as a convict to the Australian penal colony of Van Diemen's Land (modern-day Tasmania), where he achieved infamy as a bushranger and outlaw. Charles Rodius (1802 – 9 April 1860) was a German-born artist, printmaker and architect.  Trained in France before moving to England, he was transported as a convict to the Australian penal colony of New South Wales for theft in 1829. The convict era of Western Australia was the period during which Western Australia was a penal colony of the British Empire.  Although it received small numbers of juvenile offenders from 1842, it was not formally constituted as a penal colony until 1849.  Between 1850 and 1868, 9,721 convicts were transported to Western Australia on 43 convict ship voyages.  Transportation ceased in 1868, and it was many years until the colony ceased to have any convicts in its care.
