Station Officer is a rank in a number of Commonwealth and other fire services, including those in Australia, the United Kingdom and the New Zealand Fire Service.
In Australia and New Zealand a Station Officer is either the single officer on a watch in a single-appliance station, with three firefighters reporting to them, or one of several officers under a Senior Station Officer at a station with multiple appliances. In New Zealand the rank badge is a single impeller; in Australia the rank badge is two impellers. Station Officers in New Zealand wear red helmets with one blue stripe (prior to November 2013, they were yellow with one blue stripe).
In the Country Fire Authority and Metropolitan Fire Brigade Melbourne, Australia a Station Officer has one impeller, and a Senior Station Officer has two impellers
In the United Kingdom, a Station Officer used to command a station or was responsible for several watches commanded by Sub-Officers (although they may have commanded a watch on a very large station). The rank badge was two impellers, they also had a white helmet with a half inch black band around it.
More recently (2006/2007), the UK FRS has changed from a rank based system to a role based system. This change has meant the traditional ranks have gone and been replaced by a role based name for the duty performed. The two impeller marking now represents a Watch Manager. A Watch Commander (also referred to as a Watch Manager) is an officer who lead groups of firefighters and sometime in charge of a station. A Station Commander or Station Manager is an officer in charge of 1 or more fire stations.
