The prison was split into divisions, named using letters of the alphabet. • A – Short- and long-term prisoners of good behaviour. During the late 1980s, until its closure it became a scene of many monthly bashings, stabbings and bludgeonings. • B – Long-term prisoners with behaviour problems • C – Vagabonds and short-term prisoners, where infamous
bushranger Ned Kelly was imprisoned. Demolished in the early 1970s. • D – Remand prisoners • E – The hospital, later turned into a dormitory division housing short-term prisoners • F – Remand and short-term • G – Psychiatric problems • H – High security, discipline and protection • J – Young Offenders Group. Later for long-term prisoners with record of good behaviour • Jika Jika – maximum-security risk and for protection, later renamed K Division
Panopticons In 2014, archaeological work in the former prison grounds led to the discovery of three rare
panopticons (named after the 1791 prison design of British philosopher and social reformer
Jeremy Bentham) located near the A and B Divisions that were built of bluestone in the 1850s. The first uncovered and excavated was to the north of A division. The circular design, with walls coming out from the centre, created wedge shaped 'airing yards' where prisoners would be permitted access for one hour per day without coming into contact with each other. The panopticons fell out of use, due to
prison overcrowding, and were largely demolished in the early 1900s. It was awarded the 'Excellence in Concrete Award' by the Concrete Institute of Australia before being closed, eight years later, amidst controversy after the deaths of five prisoners in 1987. The design of Jika Jika was based on the idea of six separate units at the end of radiating spines. The unit comprised electronic doors,
closed-circuit TV and remote locking, designed to keep staff costs to a minimum and security to a maximum. The furnishings were sparse and prisoners exercised in aviary-like escape-proof yards. In 1983 four prisoners escaped from 'escape-proof' Jika Jika. When two prison officers were disciplined in relation to the Jika Jika escape, a week-long strike occurred.
1987 Jika Jika prison fire In 1987, inmates Robert Wright, Jimmy Loughnan, Arthur Gallagher, David McGauley and Ricky Morris from one side of the unit, and convicted
Russell Street bomber Craig Minogue and three other inmates on the other side, sealed off their section doors with a tennis net. Mattresses and other bedding were then stacked against the doors and set on fire. Wright, Loughnan, Gallagher, McGauley and Morris died in the blaze. Minogue and the three others were evacuated and survived. == Prison works ==
