This year Australia commemorates the centenary of the beginning of WWI. According to info got by StampNews.com on this occasion Australia Post is to release a new set of stamps that consists of four items. The issue is to be unveiled on the 21st of October.
This stamp issue remembers the contribution made by the defence services over the last century. Australia has maintained military forces since shortly after Federation, when the Australian Army and Commonwealth Naval Force were established by the amalgamation of the forces maintained by the states. The Australian Imperial Force (AIF) was formed on 15 August 1914, in response to Britain declaring war on Germany, because existing militia forces were unable to serve overseas.
The Australian Defence Force comprises the Royal Australian Navy (RAN), the Royal Australian Air Force (RAAF) and the Australian Army. Together these are known as the Tri-services. The three services operated more or less independently until an integrated command structure was established with the formation of the Australian Defence Force on 9 February 1976.
