Firstly BOnds are not allowed in HKG.
Secondly think a few years down the line...you will not be able to hold a captain slot in Australia. The bases are full and there is a huge number of guys requesting them. So if you join CX you will either remein an FO for your time at CX or you will have to move to HKG to be a captain.
or you can join an australian airline now and will be able to live happly ever after in Oz...lets face it they do pay better than CX!!!
