Hials, my family has traded with Asia since 1935. There is a wealth of experience, often bitter, to back up my contention.
For the record, that is that every cent Qantas puts into Asia will be lost because people like you think that Asians think like Westerners and have the same values; they don't.
It is possible to make money in Asia, but not with the Qantas mindset. To make money, plan to spend many millions over Twenty or more years with no prospect of reward to establish relationships.
Just jumping in and announcing you are open for business, as Qantas has done, will get you exactly what Jetstar has got; zero.
P.S. Relationships with not just anybody, I watched an I.T. company waste $3 million on a tender for a non existent I.T project brought to it by "the nephew of the Chinese Minister". F.F.S. Australian companies are wood ducks when it comes to dealing with Asia, start with Rio Tinto, then look at various coal companies.
