The Australian pre-decimal halfpenny coin, commonly known as a ha’penny (pronounced /ˈheɪpəni/), was the smallest denomination of the Australian Pound in circulation. It was a unit of currency that equalled half of a penny, 1/24 of a shilling or 1/480 of a pound. The coin was made to be equivalent to the British halfpenny; its dimensions, composition and values were equivalent, and additionally, the two currencies were fixed at par.
