You will find it with the ricotta and cottage cheese ILB. Have you got a continental shop in town? They usually sell it - it is a big slab, not in containers.
I've checked out the Cheeselinks website (thanks ozzy-dj) and have registered my interest in their workshops in Margaret River on June 26th and 27th. Anyone else interested? If my sister in Busselton is still away, I'll probably stay in MR for the Sat night.
