SA Premium Oysters History We first dipped our toes in the water way back in 1989 working as share farmers, By 1995 we had purchased 3 ha of prime water and jumped in head first into our first self controlled oyster venture. Our original purchase was already established with a rack and rail system and seeing as we had already had experience with both systems we decided to contine with the rack and rail, after all, If it aint broke, dont fix it. It wasnt far down the track when we purchased another 2 ha of prime water bringing our total to 5 ha
