OK. I cheated a bit to get some clues, so I won't claim the prize.
However, this may help someone else find the location, if Dora9 reckons I am correct.
The original photo resolution is good enough to see that a lot of the aircraft are B-24 Liberators which limits the location to places that saw this type during WW2.
Google Earth nailed the physical layout for me and the timeline showed how the path of the creek had changed several times, while the layout of the roads was substantially unchanged.
This place is now a bl**dy shopping centre in suburbia, and only 3km from a major airport, and 6km from the city centre.
How times have changed!
