Australian War Memorial image number 029888 is the one in question and state that the photo was taken in PERTH on 27 March 1943 during Army week, the two carriers were part of a demonstration in the streets of Perth in support of the third liberty loan...
This image is marked as in the public domain and can be posted up. If anyone has the means of posting it up on MLU please feel free to do so.
I now have NO doubt at all that it is the same vehicle.
Cheers
