 Starting from 1974, the title on the new notes only read "Australia" and the legal tender phrase was also changed from "Legal Tender throughout the Commonwealth of Australia and the territories of the Commonwealth" to "This Australian Note is legal tender throughout Australia and its territories".The $50 note was introduced in 1973 and the $100 note in 1984, in response to inflation requiring larger denominations for transactions.The $1 note was replaced by a $1 coin in 1984, while the $2 note was replaced by a smaller $2 coin in 1988.
