Shipping a small surf board from Perth to Melbourne

Good morning all, I've bought a kiteboard (150cm length x 42cm width) from a seller in Perth and I need to ship it to Melbourne, I need suggestions on ways to post it at an affordable rate. If anyone knows of such an option in Perth please let me know.

I am trying to think outside the box here too (get a motorcycle freight company to throw the board in the back of their trailer on their next trip east, anything to make the cost affordable.)

Thanks for your help!
