I've driven past the Wolf Blass winery on Sturt Highway many a time. Great place for a visit. Some good deals on the Wolf Blass here at the moment, a couple of days ago I picked up 6 bottles of cabernet sauvignon for $36 (less than 15 quid at the current exchange rate).
It's a shame the quality of Wolf Blass wines has fallen so much since they became popular in the late 90's there yellow label was something really special now it's a bit bland
