Maui to Australia Windsurfing Freight
 

I am currently living in Maui and returning home to Sydney, Australia in the next 2 weeks. I would like to send back my sails & boards with a freight company either by air or sea. There is no rush so I can wait for sea-freight, or air is fine ... but whichever is cheapest. What are the cheap options to send windsurfing gear back home to Sydney.
