The Australian penny was a small circulating denomination of the Australian Pound. It has the same dimensions and composition as the British pre-decimal penny, from which it is derived (for a time, the coins circulated in parallel and were interchangeable in Australia - but not in the United Kingdom; the currencies were fixed at par). It was worth one twelfth of an Australian shilling and 1/240 of an Australian pound.
