Although only used in special circumstances, the Australian Federal Police uniquely has separate ranks of both senior sergeant and staff sergeant. Whilst on deployment in peacekeeping operations with the International Deployment Group members of the AFP are appointed to the ranks of senior sergeant, station sergeant, superintendent, or commander.
Hong Kong
In the Hong Kong Police Force, the rank of station sergeant is senior to sergeant but junior to inspector. A station sergeant is required to have served three years at the rank of sergeant and be recommended by a selection board before being promoted to the rank. Station sergeant is the highest non-commissioned rank in the Hong Kong Police Force. Because of that, station sergeants tend to be the most experienced NCO in a unit, serving as the commander or second-in-command of a unit and/or a station if necessary. To progress to the rank of inspector, a station sergeant must undergo the same application process as other junior officers. The rank badge of a station sergeant is the Hong Kong Police badge surrounded by a wreath worn in the centre of the shoulder strap. However, station sergeants go through a 13-week training process instead of the 36-week training that other officers do. A distinctive feature of the uniform of a station sergeant is that they wear the white shirt typically worn by commissioned officers as opposed to the cornflower blue or dodger blue shirts worn by sergeants and all ranks below. However, acting station sergeants may wear the blue shirts with station sergeant insignia.
Ireland
The IrishGarda Síochána used the rank until at least the 1960s.
In the Metropolitan Police, the station sergeant, or station police sergeant, was the senior sergeant in a police station. He either acted as the station inspector's deputy or commanded a smaller station that had no Inspector. When introduced the rank insignia consisted of four chevrons, from 1921 this arrangement was replaced by a crown over three chevrons, the same insignia as a staff sergeant in the British Army. The rank of station sergeant was officially introduced to uniform grades in 1871. In 1890, a station sergeant's pay started at 45 shillings a week, rising by an annual increment of 1 shilling a week to 48 shillings a week. The Criminal Investigation Department equivalent was the first class detective sergeant, who was in charge of the allocation of cases to the detectives in each division. Originally, station sergeant was a mandatory step between sergeant and inspector, but later it became common to miss out the rank entirely and it became more of a reward for long-serving sergeants who did not wish to be promoted to inspector. The rank was never available to women officers. No further promotions to the ranks of station sergeant and first-class detective sergeant were made after 1973. The last officer to hold the rank was Station Sergeant William Palmer, who retired in 1980. The last officer to be promoted to the rank was Station Sergeant Kenneth Humm, who retired in 1983 following promotion to inspector in 1980. However, the term continued to be used to denote the senior sergeant in a station, although it was no longer a separate rank with its own insignia. Possibly the most famous fictional station sergeant was George Dixon in the long-running television series Dixon of Dock Green. An equivalent rank was clerk sergeant, or clerk police sergeant, held by the officer responsible for all administration in a division. Clerk sergeants were regraded as inspectors in January 1954.
The insignia commonly associated with the rank of station sergeant is still used within the City of London Police for those officers in an acting inspector role.
The Port of Felixstowe Police, a small British specialised police force responsible for policing the Port of Felixstowe, had one officer of the rank of station sergeant until 2015, and held the distinction of being the final British police force to employ this historic rank. In 2015, on the retirement of Inspector M. Hayward, the last station sergeant, Station Sergeant A. Miaoulis, was promoted to inspector, and the rank of station sergeant was abolished.
Royal Parks Constabulary
The Royal Parks Constabulary used the station sergeant rank until 1989, when the last incumbent, Sergeant John Stewart, was appointed to the rank.
