You'd certainly hope and expect that the project team had run the numbers for Australian conditions (and it looks like they have).
Learmonth 10000ft runway - OK (except on 40+ deg days...)
Curtin 10000ft runway - OK (except on 40+ deg days...)
Scherger 10000ft runway - see above
Darwin 11000ft runway - more than OK
Tindal 9000ft - a little more iffy but you can always offload or use Darwin.
Richmond could be the base with TOW limitations as it only has a 7000ft strip.
