Police tactical group  Police Tactical Group (PTG) is the generic term used to refer to highly trained Australian police tactical units that each State and Territory maintain to respond to and resolve high-risk incidents, including terrorist incidents. Police Tactical Groups are fundamental to the Federal government's National Counter-Terrorism Plan (NCTP) to respond to major terrorist incidents in Australia. The Plan initially developed in 1980, then known as the National Anti-Terrorism Plan, is overseen by the Australia-New Zealand Counter-Terrorism Committee (ANZCTC). The Plan requires each state and territory police to maintain a police tactical unit designated as a Police Tactical Group (previously Police Assault Group) which is jointly funded by the federal government and the respective state or territory government. The Australia-New Zealand Counter-Terrorism Committee (ANZCTC) defines a Police Tactical Group as "a highly trained police unit that tactically manages and resolves high-risk incidents, including terrorist incidents." Generally, the majority of a Police Tactical Group's planned operations and call-outs, are not counter-terrorism related, responding in their state or territory to high-risk incidents such as sieges or executing high-risk search warrants, which are beyond the scope and capability of other police units. Various state and territory police maintained 'tactical' or 'emergency' squads known by varying names consisting of police trained to use specialist equipment and weapons as far back as 1945. These sections consisted mainly of detectives and had limited capability and funding. The 1978 Sydney Hilton bombing, where a CHOGM event was being conducted at that time, saw the formation of the Standing Advisory Committee on Commonwealth and State Co-operation for Protection Against Violence (SAC-PAV). Prior to this, Australia had no formal mechanisms to respond to terrorism. SACPAV provided national consistency across all jurisdictions and made several recommendations including that all states and territories maintain a specialist police unit trained for counter-terrorist and hostage rescue situations. These units were initially known as a 'police assault group' in line with the Australian Defence Force nomenclature with their recently created (at the time) Tactical Assault Group. This saw the formalisation of many state and territory tactical units with the standardisation of all police groups in respect to training, equipment and the desired level of response. In 2001, SAC-PAV was renamed to the National Counter-Terrorism Committee and in 2012 with New Zealand entering to the Australia-New Zealand Counter-Terrorism Committee (ANZCTC).
