Light Spars in Melbourne have the dies for them and I'm sure they will have stock.

Old Bob Keeley is the owner, manager, fabricator and salesman who knows everything there is to know about RL24's!!
Just be warned, make sure you have a while to chat as he is known to go on a bit but a nicer bloke you will never meet.

Shouldn't cost you much more than $1200 and you could cut all the holes yourself and get it annodised at Allyacht Spars up your way if you wanted it done.

If you want cheap freight call Sadliers Transport. I got a 10m carbon mast trucked from Syd to Perth for about $400. Just make sure Bob wraps it up well.
