In the late 1970s and early 1980s the need for a military presence in the north was recognised, with an integrated land, sea and air surveillance network developed in response.
Part of this involved the raising of reserve infantry units that would act as "eyes and ears" in the north.
[2] Today the regiment's mission is: "To provide the Australian Army with information by conducting surveillance operations to contribute to an effective Australian Defence Force surveillance network in the North West of Australia (Pilbara Region)".
[citation needed] It is responsible for an area of 1.5 million square kilometres from Port Hedland to Geraldton in Western Australia, and from the coast to the border with the Northern Territory; being approximately one-sixth of the total Australia mass.
[3] A detailed knowledge of its Area of Operations is maintained by conducting reconnaissance patrols by foot, vehicle and watercraft; surveillance from static observation posts; and by systematic communication and liaison with police, customs, other regional authorities, and with local landowners.
