I have just gone through the process of getting a new mast in Brisbane. It was going to be too hard to transport an 8m extrusion from the association in Melbourne so I hunted around for something else and found that the Calypso cat supplier had them also. I think it was a calypso 14 mast section. Just check the dimensions before purchasing. From memory, it was significantly more expensive than purchasing from the association, but considering no transport companies wanted to touch it, it was the only option for a new mast.
