There are a few wineries scattered throughout the Zone outside of the regions. It is possible some of these wineries may be organised into regions in the future if enough vineyards and wineries are established to satisfy the requirements. However it seems more likely that most new vineyard development in NSW will be on the inland side of the Great Dividing Range.
The climate is influenced by the proximity to the Pacific Ocean, a mixed blessing, for while it moderates the extremes of temperature it also brings humidity and unwelcome rain during summer and vintage.
One plus for the Zone is that it is in a popular tourist region, allowing wineries to sell to a growing market.
What the region does show is that with research, hard work and persistence wine can be grown in climates which textbooks will tell you is far from ideal. Varietal selection is just one aspect of making good wine in difficult areas.
