Australia adopted decimal currency in 1966 following a major public awareness campaign that included television and radio advertisements featuring the characters of Dollar Bill and Mr Pound explaining decimal currency to Australians.

This radio recording features a catchy jingle, 'Out with the Old and in with the New', sung to the tune of the Australian folksong 'Click Go the Shears'. Featuring lyrics by Ted Roberts, it was voiced by actors Kevin Golsby as Dollar Bill and Ross Higgins as Mr Pound.

The decimal currency campaign was hugely successful with the public, with the character of Dollar Bill even inspiring a fan club.
