Under the direction of the Immigration Agent, Brisbane, police magistrates, customs or port officials carried out duties resulting from the arrival of immigrants at ports other than Brisbane, and from late 1863 were appointed Sub, later Assistant Immigration Agents. The Police Magistrate, Bowen was appointed the Assistant Immigration Agent, Bowen from approximately 1866, and continued in that position until approximately 1907.
Assistant Immigration Agents publicised ships' arrivals in the local press, provided information and services to immigrants such as accommodation and rations at Immigration Depots, arranged employment, and also processed government statistical information and ships' passenger lists and other immigrant records.
Assistant Immigration Agents were responsible to the Immigration Department within the portfolio of the Chief Secretary.
With the decline in numbers of arrivals at Bowen, the duties of the immigration agent decreased. The exact date of the cessation of operation of this agency has not been located, but Queensland State Archives holds records to 1912.
