Here is an historical photo of one of the Grey Nurse Spit's of 457 squadron at another airstrip called Livingston which is also near Darwin. It wasn't uncommon for aircraft to use other airstrips during the bombing of Darwin campaign by the Japanese. The Australian military built quite a few airstrips just outside of Darwin as the main aerodrome in the town was being heavily bombed. These airstrips still exist and they are located on the Stuart Highway which is the main road that connects Darwin to other parts of Australia.

Spitfire MkVIII
The MkV Spitfires were worn out from over a year of constant combat operations. The squadron got the order from the RAAF Headquarters to come back to Australia to re-equip with the new MkVIIIs which is often considered as the best of the Spitfire marks.
The initial MkVIIIs had corrosion issues which had also been found in the other Australian squadrons as well as RAF squadrons in India. New parts were fabricated in Amberley but Britain did not help and the RAAF manufacturing and supply system was slow. A similar issue occurred with the drop tanks. All these issues helped delay the squadron returning to the South West Pacific front.
The squadron relocated to Morotai which is an island south of the Philippines. The aircraft flew sweeps, scrambles and when needed strafing runs. A captured Zero was flown to Morotai in March of 1945 where several big times Australian pilots, including Clive Caldwell, flew the Zero against the Spitfires.
By mid-1945 the Australians in Morotai were far behind the leading edge of the war against the Japanese. The experienced pilots were not happy about it but it was the end result of the American and in particular MacArthur's policy toward Australia where he wanted American forces, and in particular his forces, were at the fore-front of the war effort and hence media - which was all important to MacArthur.
Despite this 79 Squadron continued constant operations in support of the Australian and American forces in Morotai. One of the missions they had to flow was destroying Japanese barges. This was partly because this was all there was left of Japanese sea power in this area. The squadron also flew strafing bombing missions against everything they could. This occasionally was airfields but a lot of the time it was anything that fired at them.
With the end of the war the squadron was involved in leaflet drops telling the Japanese troops that had been bypassed that the war was over. The Spitfires were flown back to Australia once peace had settled in and the squadron was disbanded.
