Thanks both! I will be sure to take a look at the Facebook page, and we'll revisit this idea once we've got to Adelaide in early August and then we'll be able to commit to dates. I imagine the first couple of weeks will be taken up with us getting set up and finding out how best to get around etc. We will have temporary accommodation but will need to find somewhere of our own to move in to, so I'm sure this forum will help with that (info on suburbs etc).
We are a couple in our early 30s with no kids, so it would be great to meet others in the same situation but we aren't too fussy really!
Thanks again for your replies.
