Mr. Jones is a "Banana Bender" according to what I researched about Australian Slang.
Some interesting slang :
beyond the Black Stump - a long way away
Bondi cigar or brown-eyed mullet - a turd in the sea
Bush oyster - a nose booger
Crack a fat ( I'll let you look that one up yourself)
Dingo's breakfast - a yawn, a leak, and a good look around (i.e. no breakfast)
Dunny budgie - a blowfly
Aussie Salute - brushing flies away
Shark biscuit - somebody new to surfing
There are also many slang terms that parallel what we use in the U.S. and
here in Canada.
