Its not an Australian Carrier, It's an Australian pattern carrier, built in New Zealand. Newzealand built about 630 carriers, and then the War council ordered another 2000. Production was started, and when things were well underway, with about 500 carriers built, the war council shifted its order to Ford of Canada. At the wars end ther was a lot of new carriers. The Army drew on them. This carrier was one of those carriers that was converted to a Mortar carrier, post war.

The one at the back is British, the one at the front of the photo is Canadian.
