Mount Thomas and the nearby small settlement of Widgeree are overseen by the St Davids police district, based in the larger town of St Davids (also fictional), which has a population of just over 68 000. Successive inspectors, Ted Faulkner and Russell Falcon-Price, are based there, as is Inspector Monica Draper of Ethical Standards Division (E.S.D.). The C.I.B. in St Davids is supervised by a Detective Sergeant who is also responsible for the detectives based at Mount Thomas, though this is very rarely mentioned or explored after being a major plotline in the first season. St Davids Police Station also hosts a district Forensic Services department, but other more specialised units, such as the Homicide Squad, Special Operations Group and Accident Investigation Squad respond from Melbourne.
