Hi Rick always good to see more Aussies here.
Trusty has a very good name here, you should be fine.
SA is an awesome watch - but you better like them BIG!

I have used Josh as well (note he has a new site - old one got hacked) - super great service.
SEAD as a very good name as well.
Do your research on your dealer, but all the approved ones here are good - importantly learn how they like you to contact them, place your order and give payment. Some like PWC are very specific, but if you follow their guidelines you should be fine.
I have had watches shipped from China, Thailand, UK and USA, all without problems or customs issues.

Enjoy
