1960-1964: The 1/6d Christmas Bells definitive, part of the flora series, replaced the 1/6d Hermes definitive which had been on issue since 1949. This design was originally engraved as a 1/7d denomination, to replace the 1/7d Elizabeth II definitive, but the October 1, 1959 rates changes rendered that denomination obsolete, and the design was adopted for the 1/6d stamp instead. Coloured paper was used to achieve a two-colour effect.
1959-65: The 2/- Flannel Flowers definitive, the first stamp to be issued in the flora series, replaced the 2/- Aboriginal Art definitive which had been in issue since 1948.
1959-64: The 2/3d Wattle definitive was a new denomination required for the airmail rate to Europe. Coloured paper was also used to achieve a two-coloured effect.
1964-66: The stock of yellow-tinted paper was exhausted during 1964. Initially, it was intended to re-issue the 2/3d Wattle design as a photogravure printing, but when pressure of work made this impractical, it was decided to continue the current design, printed on normal white unwatermarked paper.
1960-64: The 2/5d Banksia definitive was a new denomination required for the combined letter postage and registration fee. The design had originally been conceived as a 2/6d value to replace the Aboriginal design, but was changed following the October 1, 1959 rate increases. Coloured paper was used to achieve a two-colour effect.
1959-64: The 3/- Waratah definitive was a new denomination required primarily for telegram charges.
