The Northern Territory Police Force is the police body that has legal jurisdiction over the Northern Territory of Australia. This police service has 1,537 police members (as at 31 July 2019) made up of 79 senior sergeants, 228 sergeants, 839 constables, 208 auxiliaries, and 73 Aboriginal Community Police Officers. The rest of the positions are members of commissioned rank and inoperative positions (as of 31 July 2019). It also has a civilian staff working across the NT Police, Fire and Emergency Services. Police in the Northern Territory are part of a tri-service: the Northern Territory Police, Fire and Emergency Services with the Commissioner of Police as the CEO of the tri-service. History The Northern Territory Police traces its roots back to the South Australian Mounted Police from 1870 when Inspector Paul Foelsche and six other police officers arrived in the Territory. A small rural constabulary (part-time force) had existed earlier but was disbanded. The Native Police Corps was formed in 1884. Their role was mostly as a security force to protect the early inhabitants of the Northern Territory than as a police force. The current NTP came into existence in 1911. In 1931, the two Territories Central and Northern became the Northern Territory of Australia and the authority of the Commissioner of Police was established in the Administrator of the Northern Territory, in Darwin. In December 1869, the governor commissioned Paul Foelsche, a Corporal in the SA Mounted Police stationed at Strathalbyn, to be the first sub-inspector of police at Palmerston. He sailed for Darwin soon afterwards. The police uniform then worn in the Territory was the same as that worn in South Australia. It consisted of a short cut-away blue serge tunic with nine regulation buttons, silver twisted cord shoulder knots, black braid on the sleeves and silver chevrons for non-commissioned officers. The riding breeches were dark blue corkscrew serge with a white stripe. The earliest firearms used were Snider–Enfield rifles and carbines firing a .577 calibre cartridge. Later, Martini–Henry rifles were used, and Webley revolvers were issued. Like their predecessors, the Rural Constabulary at Escape Cliffs, the first detachment of police at Palmerston had as their first responsibility the maintenance of law and order in the community. The police were frequently engaged following the discovery of gold near Pine Creek in 1872. Stations were established at Adelaide River, Yam Creek, Pine Creek, Roper River and later at Daly
