Here's another "CMP in the background" from the same site, this time a CGT 8 at Buna. I've come across other pics of CGT 8s being landed here, and even some brief footage of a CGT 8 with short 25 pdr in tow, turning off the beach into the jungle. From memory it's on the ANZAC 3-disc series - I shall locate again and post here.
Here's the link to the image below:

On the same site can be found some rare pics of cab 12 FATs in Australia:
