 The $1 (10/-), $2 (£1), $10 (£5), and $20 (£10) had exact exchange rates with pounds and were a similar colour to the notes they replaced, but the $5 (£2/10) did not, and was not introduced until May 1967 when the public had become more familiar with decimal currency.The original bank notes were designed by Gordon Andrews, who rejected traditional Australian clichés in favour of interesting and familiar subjects such as Aboriginal culture, women, the environment, architecture and aeronautics.Notes issued between 1966 and 1973 bore the title "Commonwealth of Australia".
