Fear if we don't let Australians fly to Fiji & other Pacific tourist islands soon, they will be offered 100 billion dollar Chinese loan each, which they'll never be able to repay, so china will simple move in.
I am not sure any of the Pacific nations are in line to get 100 times their GDP from China, but I get your drift. Unfortunately, PNG knows this game well and plays Australia off against China whilst either wasting the money on fantasy Skyrail plans, or merely through blatant corruption. If Australia wants to keep the Chinese at bay, it should insist on 99 year leases for key bases in return for investment.
Handing Air Niugini $140m is like making the local alcoholic manager of the Bottle Shop.
