Ok i copied a piece of the link:
Netherlands East Indies B25 Mitchell bombers in Canberra 1942.
The NEI had ordered and paid for aircraft from the US and three squadrons were formed in Australia. No.18 Squadron formed in Canberra on 7 APril 1942 flew its B25 Mitchell bombers. The majority of the aircrew were Dutch, mostly from the NEI. Others came from Dutch training courses run in the USA and the rest were Australians. Most groundcrew were Australians from the RAAF. The B25s formed a composite squadron within the RAAF that flew over 900 operational sorties during WW2.

In June 1942 the squadron consisted of 242 Dutch and 206 Australians. The Squadron was commanded by Dutch officers but was under the operational command of the RAAF, being part of 79 Wing.
An early success was the sinking, on 5 June 1942, of a Japanese midget submarine 115 km east of Sydney by Captain Gus Winckel in a B25. Apparently the midget submarine, having just attacked Sydney, was lost and so unable to rendezvous with the mother ship when sighted on the surface.
Later in the war, No.18 Squadron moved to Bachelor in the Northern Territory, and flew missions to the north of Australia and back over the NEI.
From there they moved into the South West Pacific, operating from a number of fields, and eventually flying over 900 operational sorties.
