Naval slang has been used since the formation of the Royal Australian Navy (RAN), much of it taken from the Royal Navy. The following is a brief collection of terms and sayings that may be heard in most RAN ships or establishments.

Over the years, hundreds of naval words, terms and expressions have found their way into everyday language. Some of these include ‘the cat is out of the bag’, ‘above board’, ‘long shot’ and ‘over a barrel’.

The term ‘chock-a-block’, meaning ‘full’, is a naval expression. It comes from the days of sail, when blocks and tackle were in common use in a ship’s rigging. When the lower block of a tackle was run close to the upper one and could not be hoisted higher, they were said to be ‘chock-a-block’. 

The term ‘slush fund’ was also originally a nautical term. The slush was the fat or grease skimmed from the top of the cauldron when boiling salted meat. Ships’ officers would sell the fat to tallow makers and the proceeds kept as a ‘slush’ fund for small purchases for the ship’s company.
