Hi, wondering if i could get any help/advice?

I am coming over for a year on a working holiday and looking to ship my kit over as it is seems far more economical than buying new stuff.

I was wondering whether I will need to pay import duty on windsurfing kit?

Thanks, Tom

check the rules here: www.homeaffairs.gov.au/

note:
-if you bring your gear as "accompanied baggage" (i.e. check it in on the flight with which you're coming over) you'll generally be fine (apart from excess luggage fees by the airlines of course!)
-if you're shipping it cargo ("unaccompanied") you might be asked to prove that you "both owned and used" your kit overseas for 12 months or more when you clear customs

(disclaimer: this is not legal advice!)

agree - virgin is ok for traveling with gear. but always check the airline's baggage rules, literally up to the minute before you head out to the airport. rules are different between airlines, and change often even between return flights (!). some charge by the piece, others by weight and/or dimension, or a combination of both...

I sent three sails and some other stuff with air cargo. If you declare that your gear is older than 12 month there's no duty. However there is a fee for quarantine clearance. I don't remember how much it was, but way more than I expected.

I had to go to customs twice, first time was just paper work and the second time I could pick up my gear. Not fun when you have to take the bus...
They are really picky that your gear is clean. I had some grass stuck on the velcro on the sail, and I had to clean it. If you bring a wetsuit, they will ask you if you have used it in freshwater. If you answer yes, they will sink it into some detergent and you will have to pay an extra fee. This doesn't apply if you only used it in saltwater.

All in all, If you can find an airline that accept your gear as luggage, and it's not TO expensive, I would do this instead of send it.
