On the blog of Geoff Bilbrough I found a most useful tool: the Australian Wine Region Map. If you are planning a trip to Australian and you want to visit some wine country, this map is exactly what you always wanted.
On Geoff’s link, the “Wine Wine Wine” (which by the way is a wonderful informative site) the map looks like the sketch below in the left corner:
I played a little around with the Google based map, and found it amazing, especially the Yarra Valley part. Unfortunately, our wine region, the Upper Goulburn Wine Region is not (yet) on the list of Australian wine regions.
The interactive map allows you to select a wine region and/or a winery so that you can plan your winery tour. It prints out the map as well, if you like. Precondition is of course that the wine region and the vineyard/winery you intend to visit are somehow included in the system.
I will try to use the tool soon when we all go to Australian for the winter break. I’ll report back to you.

Dear Rainer,
thanks for this perfect update. I promised to my wife that we will have vacation in Cambodia and Laos next time but after looking to this great australian wine map I’m sure that Swan Valley is defintely the better choice. Sometime you can’t overrule your heart…
Thanks again, have a great time, greetings from Hamburg
