In 1849 William Craig and his son Jim, erected the first Police Station. In the same locality shortly afterwards Ned Anderson built the first Court House.

With the settlement that already taken place in the Warwick district, which included many ticket-of-leave men, the New South Wales Government decided to extend the control already exercised by Commissioner Rolleston, and formed a Police Station at Warwick in 1847. Sergt. Thomas McEvoy was placed in charge, with Constables J. Hourigan and Jerry Scanlan. Their barracks was the first shepherds hut built by George Leslie on Canning Downs, and occupied a site near Queen's Park. A slab humpy was afterwards built as a Court House. At the time, Sergeant McEvoy had William Clunes as his Constable, the other two men having gone, apparently with Mr. C. Rolleston, or better known then as Eton Vale. What a wise selection of Sergeant McEvoy turned out to be was immediately apparent. This officer, by much patience, the tactful, just, and sympathetic application of discipline, created an atmosphere of freedom among all classes. He at once became a prominent resident, and later on, when Warwick elected its first Alderman, he was chosen as one of the Council, and afterwards its became Warwick's second Mayor. Sergeant McEvoy resigned in 1859. And passed away in 1866.
