FlagsTwo individual flags and one group of four are regularly flown when the ship is open for inspection.
From the jack staff (at the bow) the Australian National Flag – the Blue Ensign – is flown.
It was flown when the ship was alongside or at anchor and is raised or lowered in the same manner as the White Ensign. Protocols for flying flags at half-mast are observed.
From the port side yard of the foremast a group signal flag and pennants signalling the ship’s number: J 244.
From the ensign staff (at the stern) the White Ensign is flown.
From the formation of the Royal Australian Navy in 1911 until 1967 RAN ships flew the White Ensign. HMAS Castlemaine flew the White Ensign during her entire operational life. It is deemed appropriate to fly it now, as the ship is a museum ship and is not in commission.
In 1965, the Minister for the Navy informed The House of Representatives the Government was looking at variants of the white ensign which would be unique for Australian naval ships. In 1966 The Naval Board approved the design described as “a white flag with the Union Flag in the upper canton at the hoist with six blue stars positioned as in the Australian Flag.” The new design was submitted to Her Majesty Queen Elizabeth II, and Royal assent to the new design was granted on 7 November 1966. The new ensign was flown from all RAN ships from 1 March 1967.
