I sent a pair of wheels to Tasmania(Chris King/Bontrager race lites) was it
at a cost of £80 Royal mail international recorded. I picked this service purely because its such a big well known and i would think well run company and that you get a signature at the other end.
As they charge for volume the space the bike itself doesnt occupy you get charged for also so you either pack it really tight in a small box and hope it doesnt get bashed around or go for the bigger well padded box and pay a premium for the lost space. I was advised to cover the entire box with sticky tape as to make it reasonably waterproof. Apparently it can rain quite heavily down your neck of the woods and i was instructed on tales of boxes disintegrating on the runway/yard.
There is a good bike box maker i found in a general surf and it looks a great idea,very well thought out .The box is triangular in shape so you leave the bars on and remove the front wheel,some other bits all of which have built in compartments for them
Unfortunately ive lost the link but ill have a look see
