Listen to bubble, and don't get any ideas of buggering off with the endorsement, until you make F/O (4-5 years) the licence you get is not worth a pinch of

30K HKD /month is fark all in HKG, hell, its fark all in Oz ! To add insult to injury, you will never get housing or education allowance, which are MASSIVE costs in HKG.
Enjoy
