TxTD.........Thanks for posting the photograph. I admire your skill at being able to make it appear on our screens.....!!!
I have checked through the history of the Australian deH 86s (John Hamlin's book The deH Dragon/Rapide Family). Eight were registered to the RAAF during the course of WWII. A31-1 to A31-8.
A31-1, -3, -4, -7 & -8 were converted to air ambulances.
A31-1 & A31-4 served in New Guinea, so it would seem your photo shows one of these.
A31-3, A31-7 & A31-8 served in Egypt. (-8 for only about 4 months).
Hope this proves to be of interest...........
