Fantastic @tielec, great suggestions and thank you for the tipsHi Matt_H, Picardy is a must visit in Pemberton - Bill produces a particularly interesting interpretation of Pinot that is worth trying (amongst others) - it is by appointment only though, so make sure to call. The Truffle & Wine Company also have some good wines and good food.
In Geographe Capel Vale make some decent drops and would be well worth a visit.
Enjoy your trip!
