Thanks fellas.
I picked out my live rock on Wednesday night. Was actually a really awesome experience, I called the supplier on Wednesday ( who i had been in contact with) and he said its my lucky day as the collector was dropping off a fresh load. So i was picking my pieces as they are were unloaded from the truck. I must say some of the best live rock I've seen in terms of formations. I got one piece that will be a stand alone bommie on it's own, probably close to 3' across, 1.5' wide and tall, and only weighed 10kg (22lb). very porous and full of caves and over hangs.
Tanks filling at the moment with RODI water, hopefully pick up the rock either tomorrow or monday evening! almost there....
