Try to find the spot where the photographer was standing.
In the bottom left hand corner, there is what seems to me to be the bow of a DUKW amphibious vehicle.
535 of these were sent to Australia as part of the United States Lend Lease program, and entered Australian Army service in 1942.

Thanks Bob. You can see more of the vehicle in this shot from the same series: acms.sl.nsw.gov.au/item/itemLarge.aspx?itemID=29402
Thank for the link. That's a DUKW for sure.
Sam Hood was a monster, astonishing captures from the photographic point of view with exquisite framings, very interesting photo collection.
I wonder how many people lived at Ingleburn then.
