If it means anything, I overheard a few HKE pilots on the bus from the terminal to Tung Chung debating if they would even finish their contracts. My guess is the pay would be ok in your home country, but they did not expect to have the costs that they do in HK. It makes perfect sense.
I've mentioned it before, but I will again (prices in HKD):
- Housing: Minimum 20k for original condition in CC in Tung Chung 3bd/2ba, a new 1 bedroom in Century Link, minimum 14k
- Schools: You're not an HK/HKPR so minimum 7k for full day starting at age 2, this is the low end
- Eating Out: A nice pub meal, minimum 300 for two people assuming 1 adult beverage each
- Groceries: Buying imported, or from China. If imported, 30 for a cucumber, 60 - 100 for a medium quality steak, etc... It'll run out fast.
If you're a local, and can live with your parents, it may be ok.
