The Australian twenty dollar banknote was issued when the currency was changed from the Australian pound to the Australian dollar on 14 February 1966. It replaced the £10 note which had the same orange colouration. There have been only two different issues of this denomination: a paper note which had a gradient of yellow and red, with a distinct orange background, and a polymer note which can be recognised for its distinct red colouration, however often mistaken for an orange colour. The polymer note was issued in 1994.

According to Reserve Bank statistics, at the end of June 2007 there was a net value of $2,846 million in $20 notes in circulation representing 7.1% of the cash value of all issued notes. Actual banknotes in circulation account for 15.8% of all denominations, or 142.3 million banknotes.^[1]

Since the start of issuance there have been 14 signature combinations, of which the 1967 issue is of the greatest value, issued for 1 year only; and the 1989 Pillip/Fraser being issued for less than a year.

From 1966-1974 the main title identifying the country was Commonwealth of Australia, there were 146,960,000 notes issued in its life. This was subsequently changed to Australia until the end of the issuance of paper currency for this denomination in 1994 with 1,661,970,048 of these notes being issued.
