Lucky you! Wish I was going!
I'm not Australian. I live in USA but I have a friend who lives in Murray Bridge, South Australia. I wrote to him & asked your question. This is what he wrote back.....
"Victor Harbour is a nice place to visit. Glenleg is a nice place... Hahndorff is a nice tourist town very German I guess. I don’t really know much else around here. More familiar with Victoria. Adelaide is a nice clean city. Though it is relatively small as far as capital cities go."
Not very helpful. I wrote back and said 'don't ever go into the tourism business'. lol
I did a quick search in Yahoo & got these:
http://www.touradelaide.com/
http://www.southaustralia.com/home.asp
There are tons of sites out there if you want more information but I thought these 2 looked pretty good. When you get back, please let us know how it was, where you went & what you did. I'd love to hear all about it. Pictures would be nice too.
Wishing you safe travels! And hoping you have a great time!
PS: btw... where are you from?
