The Western Australia Police Force, colloquially WAPOL, provides police services throughout the state of Western Australia, an area of 2.5 million square kilometres, the world's largest non-federated area of jurisdiction, with a population of 2.66 million, of which 2.11 million reside in the Perth Metropolitan Region. History Early history The genesis of the police was the appointment of a sheriff by Captain Stirling on 18 June 1829, as part of the proclamation of the Swan River Colony. The proclamation provided for the appointment of a sheriff having under his direction a high constable, constables, bailiffs and surveyors of highways. The sheriff still exists as an officer of the Western Australian Justice Department—no longer having jurisdiction over police or highways. The sheriff retains responsibility for enforcement of court judgments and the administration of jury service. Police continue to carry out sheriff and bailiff duties, particularly in remote country locations. Early colonial policemen were recruited by magistrates and worked part-time. They were paid only for specific tasks, such as one shilling for serving a summons. By 1830, there were fifteen part-time constables in the state, of whom five worked in Perth. A mounted force was established in 1834, proving unpopular with citizens on the grounds that it was not efficient and was being paid out of their taxes for duties which the military should be performing. It was involved in the "Pinjarra Massacre", in which Captain Ellis, the police superintendent, was killed together with a large number of Aboriginal people. The first full-time constable for Perth was appointed in 1840. The Legislative Council passed a police ordinance in 1849 that outlined police powers and responsibilities. An organised police force was formally established in 1853. Convict period After convicts started arriving in the colony in 1849, the police acquired the duties of registering and supervising ticket-of-leave men. By 1870, after transportation had ceased, some 1,244 ticket-of-leave men had to be supervised by 146 police employees. Applicants for police service were required to be aged under forty, literate and physically fit. Leave was difficult to obtain and officers were not to appear in public when out of uniform. Until the end of the nineteenth century, the monthly pay day was marked by a parade with band. A Criminal Investigation Department was set up in 1873, although two detectives had been sent out from Britain in 1854. A fingerprint bureau was set up in 1902.
