 <unk> his tour with No. 79 Wing , Eaton was appointed Air Officer Commanding Southern Area , Melbourne , in January 1945 . The German submarine U @-@ <unk> operated off southern Australia during the first months of 1945 , and the few combat units in Eaton 's command were heavily engaged in anti @-@ submarine patrols which sought to locate this and any other U @-@ boats in the area . The Air Officer Commanding RAAF Command , Air Vice Marshal Bill Bostock , considered the sporadic attacks to be partly " nuisance value " , designed to draw Allied resources away from the front line of the South West Pacific war . In April , Eaton complained to Bostock that intelligence from British Pacific Fleet concerning its ships ' movements eastwards out of Western Area was hours out of date by the time it was received at Southern Area Command , leading to RAAF aircraft missing their rendezvous and wasting valuable flying hours searching empty ocean . There had been no U @-@ boat strikes since February , and by June the naval authorities indicated that there was no pressing need for air cover except for the most important vessels .
