Dunno, Wikipedia didn't mention this. Only happened in 1966 though, they had australian pounds before that.
They did. But they had dollars even before that. I was trying to explain the rationale behind calling it "dollar" and not something else. Once the pound went away, a lot of countries reverted to calling their currency "dollars", because the term existed worldwide even before the pound was imposed on them. From the same wikipedia page you might have checked:
http://en.wikipedia.org/wiki/Australian_poundAustralia's first coinage was issued in 1813 by the colony of New South Wales by punching the middle out of Spanish dollars. This process created two parts: a small coin, which was called the dump in Australia, and a ring, which was called a holey dollar. One holey dollar was worth five shillings (a quarter of one pound sterling), and one dump was worth one shilling and three pence (or one quarter of a holey dollar). This was done in order to keep the coins in New South Wales, as they would be valueless elsewhere.
Anyway, this is waaay off topic. I hadn't read about it till you brought it up. Was an interesting digression, though
