There is an excess baggae allowance but sadly I cant tell you what itbis off the top of my head. Perhaps a newjoiner can assist.
There is also ID90 on air-freight. This is not speciically for joining but an annual entitlement. Again, I cant tell you how much we get annually.
Also, CX with give you a HK$10,000 interest free loan, to help cover the costs of getting yourself set up. This is in addition to the HK$10,000 they give you as a gift when they set up you bank account.
As a brand new DESO, when you move to HK from Adelaide, your HK bank account will have approx HK$42000 (US$5500) in it (you can then ask for the loan in addition to that)
The HK$10k loan is deducted from you pay at HK$1000/mth over the 1st 10mths.
