Here's where it gets tricky...
First, you need a (easily intimidatable) relative or a (sucker for a) friend who is able to organise your stuff to be taken out of storage and sent to the CX freight terminal whilst you are in HK.
Failing that, you can travel ID90 back to your home port on one of the few days off you have in training, work like a blue-arsed fly organising the move logistics yourself, and shoot back in time for your next training event!! Clear as mud??
Put simply, there's no easy way to do it and everyone's situation varies. With a family/young kids you will probably want to get out of the Headland ASAP and set up shop so your family can join you, in which case; get your game face on for the first couple of months in HK 'cause you're gonna be busy. If you're a singly whose only concern is where your next Russian whore and "eight-ball of Crack" is coming from, then take your time living in the hotel and wait 'til LFUS starts, by which time you'll have 5-7 days between trips leaving plenty of time to jet back and organise your furniture.
And no, the company won't come and collect it from your Oz temp storage for you - it's your responsibility to pack it/get it to the CX freight port.
Who would have thought moving internationally and starting a new career could be so complicated?!?
