4.2 The Security programme aims to provide safe and healthy conditions that are consistent with human dignity for all inmates, thereby supporting security for both personnel and the public. It remains the programme receiving the highest allocation - in 2011/12, R5,598 billion i.e. 34 percent translating to a real increase of 3,3 percent i.e. R162,2 million. Growth in expenditure is expected to increase at an annual rate of 7,1 percent reaching to R6,4 billion over the medium term. Much of this growth can be ascribed to the intended improved security at correctional centre level as well as to the operational costs of the Brandvlei, Van Rhynsdorp and Warmbokkeveld correctional centres that are currently being upgraded. Expenditure on consultants decreased from R14 million in 2009/10 to R89 000 in 2010/11 largely because control security rooms will now be manned by correctional officers.
