A Boonie is Australian Slang for the $100 bill. Whatâs Green and Gold and always scores 100? Aussie legend David Boon. First petitioned to the Australian People by Hal Douglas. $20 notes = lobsters, $50 notes = Pineapple, but Boonies are for the win!
âCheck out the Boonies on him mate, the dudes loadedâ. âHow much for the quarter?â âJust a Boonie Broâ.
