It is my understanding that WW2 vehicle supplies were all in the same colour, "Service Green", regardless of what service they went to when new. What happened Post war as vehicles were refurbished is anyone's guess but this is when most RAAF (& Navy?) vehicles would have reverted to RAAF Blue in colour. Full rebuilds may have meant stripping all existing paint and starting again.
