For people living in Australia and New Zealand, there are two existing web resources:
(1) an informational website: http://scdoz.blogspot.com/
(2) a discussion group: http://groups.yahoo.com/group/scdoz/
As Matt, the moderator of the group, describes them:
The idea of the group and the site are to provide information, links, and resources for people in this part of the world to apply the diet.
If you have a question about following the diet, please use these resources.
