History of Fremantle Prison: The history of Fremantle Prison, a former Australian prison in Fremantle, Western Australia, extends from its construction as a prison for convicts, using convict labour, in the 1850s, through to its modern-day usage as a tourist attraction.  The design for Fremantle Prison was based on the Pentonville Prison in Britain, and it would be the longest, tallest prison cell block in the southern hemisphere.  Construction began in 1851, and was completed by the end of 1859.  The prison was transferred to the colonial government in 1886 for use for locally sentenced prisoners.  Following a Royal Commission held in 1898−99, some changes were made to Fremantle Prison, including knocking down the inner wall between two cells, introducing a prisoner classification system, and constructing internal walls in the main block to create four separate divisions.  A new cell block, New Division, was completed in 1907 and occupied in 1908.

The prison is now a museum, tourist attraction and function centre.

Staff and prisoners of Fremantle Prison: Staff and prisoners of Fremantle Prison occupied the former prison on The Terrace, Fremantle, in Western Australia, between 1855 and 1991.  Fremantle Prison was administered by a comptroller general, sheriff, or director, responsible for the entire convict or prison system, and a superintendent in charge of the prison itself.  Prison officers, known as warders in the 19th century, guarded against escapes, enforced discipline, oversaw prisoner work, and instructed inmates in trades.  Officers worked under stringent conditions until they achieved representation through the Western Australian Prison Officers Union.  Convicts were initially of good character, as potential future colonists, but eventually less desirable convicts were sent, until the end of transportation in 1868.  As a locally run prison, Fremantle's population was generally short-sentenced white prisoners in the 1890s, with very few Aboriginal prisoners; however, by the late 20th century, most prisoners were serving longer sentences, a higher proportion of them were violent, and Aboriginal people were over-represented.
