The first stamp issue in a five year series to commemorate Anzac Day was released by Australia Post last week.
The series is designed to tell the chronological story of Australia's involvement in World War I.
Each of the five stamp issues has been developed in conjunction with the Australian War Memorial to encompass key events, battles and individuals relevant to each year of the centenary.
The 2014 stamp issue marks Australia's involvement in the first months of war, with five domestic base-rate (70c) stamps, the first entitled War Declared! - Volunteers queuing to enlist in Sydney.
The second; Australians in Action - The seizure of German New Guinea - the first action in which Australians were involved and third; Troops Depart - The enthusiasm of new recruits as they departed for Europe.
The fourth is entitled Training Mena Camp - Australians with a mascot at Egypt's Mena Camp and the fifth; Our Boys - Three unknown soldiers in a studio portrait, representing the tens of thousands of young men who fought in a war half a world away.
Between 2014 and 2018 Australia will commemorate 100 years since WWI, a conflict which helped to define our country.
Australia Post manager philatelic group Michael Zsolt said during the next five years of commemoration we hope to join all Australians in honouring the contribution made by Anzacs.
"We hope that these stamps serve as a symbol of our appreciation to those who made the ultimate sacrifice," he said.
The WWI centenary stamp issue comprises a mini sheet, stamp pack, first day cover, maxi cards, medallion cover, booklet of 10 x 70c self-adhesive stamps and two postal and numismatic covers.
The stamps and associated products are available from the local Australia Post on Commercial Road, via mail order on 1800 331 794 and online at auspost.com.au/stamps while stocks last.
