Decimal currency was introduced in Australia on 14th of February 1966. The new 1 dollar banknote was put into circulation on this date. The design changed very little between its introduction in 1966 and the final issue in 1982. Two things in the design that were altered were the legend "Commonwealth of Australia" along the top of the note (this was altered to "Australia" in the early 1970's) and the movement of the security thread through the note from the centre to the side. The signatures ranged from Coombs/Wilson in 1966 to the final issue in 1982 signed by Johnston/Stone.
