"Crossing the Equator" Ceremony 1966

Captain Bob Millagin, Charlie Company 5RAR, as the selected Army representative is the subject for treatment by the navy in a Crossing the Equator ceremony aboard HMAS Sydney in April 1966.
The Australian Navy website states et al.
The custom of nautical ‘crossing the line’ ceremonies has its origins in ancient times. The Phoenicians of the Mediterranean would conduct ceremonies dedicated to the god of the seas when passing through the straits of Gibraltar. The Vikings of Northern Europe had similar practices.
The Royal Australian Navy (RAN) adopted the ceremony after its first voyage from England to Australia in 1913.
The ceremony is dedicated to the mythological god of the seas, Neptune or ‘Neptunus Rex’ (Ruler of the Deep), known as the ‘Majesty’. A senior member of a ship’s company, often a chief petty officer, usually portrays him. Other senior members of the ship’s company, dressed in vivid and colourful clothing, join King Neptune.
Sadly, Capt Milligan was killed in action along with his company commander and NZ artillery forward observer in February 1967.
