Enchilada,
Hey, I saw on Ebay not too long ago that some guy in Australia was selling some Aussie/New Zealand Defence Force rations. The picutres showed only one type of meal. Most of it was the tan retort pouches, like US MRE's, with some civilian looking writing on the front on a white paper label. All of the meal(s) and condiments were bagged in another clear plastic bag. Didn't se any cans at all.
I was tempted to buy one but with the dollar kind of low right now the shipping was just a bit too much for me.

He did have several that he put up and they went for alot of money.

Haven't seen any around now. You might try checking Ebay. Australia and type "ration" in the search engine. One thing that kind made me wary was the fact that I wasn't sure that it was "genuine". After looking at the new Aussie Ration page by Kman I now know it wasn't but maybe some spin-off or maybe a ration designed to look military but designed for the civilian disaster folks
