I'm not sure what you are suggesting HH? Australia fund an Indonesian military rebuild? I'd be pretty sure a lot of our aid is sensibly going into CT ?
It's not as simple as you suggest. The Indonesians buy some Chinese weapons too and their China policies still seemingly fluid. Even aiding the logical build up of Indonesian maritime and air bases in Kalimantan say, would be complicated considering the Malaysians.
Back to the F35 and the ADF. I'm guessing that more tankers are on the cards in the medium term as the ADF is pressed toward more long range surveillance and intelligence support to the north.
