Just to say we had a wonderful time on our three week trip with OzXposure. We were in a bus with twenty somethings plus one lady more our age which meant we were continually challenged in what we did which was great. We certainly saw more and did more than we would ever have done on our own. The food was good and the accommodation fine - we slept under the stars for at least eight nights. Both the tour guides were good and knowledgable - they drove long distances yet still organised us in getting camp up etc and were good fun as well. I went sky diving for the first time and abseiled down one of the gorges.
If other people of our age are interested in these trips the things I would feedback are that you do need to be used to being active and are fairly fit and that you need to be able to go with the flow.
