Who on an Australian base would give 47 c + 15 c = 62 cents of most dollars of their 'hard earned' to two governments, one of which is a country they don't even live in? It's insane! It wouldn't be worth working!
Maybe the Hong Kong Government could start taxing QANTAS pilots who regularly bid HKG patterns.
If this isn't resolved CX had better brace themselves for two things:
1. Large numbers of pilots and families coming to Hong Kong with the associated costs
2. Large numbers of pilots who don't want to come back resigning.
