Australian readers will be pleased to see the new stamps being issued by Australia Post this year.
They should make Australian stamp users think about why these people are on the stamp.
They are, from left to right: Peter Carey, Tom Kenneally, David Malouf, Colleen McCullough, Bryce Courtenay, and Tim Winton,

Apparently there will be 2 stamps for each: one "grey-haired", and another with a younger image.

The Australian Legends is an annual series of commemorative postage stamps issued by Australia Post since 1997. The stamps commemorate living Australians who have made lifetime contributions to the development of the Commonwealth's national identity and character. Prior to 1997, the only living persons who could appear on Australian stamps were members of the British Royal Family.
