Joe,
The tank in question is the Mephisto. It was supposed to be sent to the AWM, but when it arrived in Brisbane the State governor had it unloaded and dragged to the Queensland museum. He then petitioned the Prime Minister to keep it here based on the fact that it was captured by a Queensland battalion. The tank is currently on loan to the AWM in Canberra.
Interesting the AIF stole it a second time. At the end of the war the British government claimed it, but the AIF stole it and had it shipped to Australia before the British could get their hands on it.
When it comes down to it we are a nation of theiving bastards! Oh and the previous photo is one of the most iconic pictures of the AIF from WW1 in my view.
Regards
Steve
