NC, dont work for any of the afore mentioned so have no axe to grind, but am looking at, and do have friends in, HK.
Dumbing it down to my level, to bank 100k in Oz you have to be paid ( roughly ) 140K to earn 100Kaud at CX or Dragon dont you only have to earn 100K ? ( due to 13 month bonus ?? and low tax )
Also there is no hsg allow in Oz, if you are lucky/unlucky enough to live in Sydney and dont want to live in a war zone or drive 1 1/2 hours to work you can conservitively kiss goodbye to 2000k net a month ( 24 a year ), also contrary to popular belief ( mainly from those " lucky " country die hards ) it is not a cheap place to live and in the top 5 ( overall ) taxed countries in the world ( consider that higher taxed countries look after you when you retire, not " pi55 off, you own too many things " )
I have friends at QF who would be on around 160-170K as an F/O ( more than 10 years of service ) and would be losing circa 50K in tax. That takes them down to say 110-120aud minus rent?
