did some research.....one theory is that the aussie term thongs is derived from their perspective of jandals looking like G strings for the feet
one kiwi website says.......
"Should you meet a friendly Australian on the feet-burning black sands of Piha beach in summer, therefore, don’t be alarmed if he tells you something along the lines of… “Struth mate, it’s so f**king hot I had to wear me sheila’s Thongs.”Unless, of course, he is actually wearing two pairs of his girlfriend’s underwear. In that case, smile politely, and try to move on, remembering that it isn’t his fault he’s not right in the head. He is, after all, only Australian.
