I've booked a holiday to Oz in September and although most of it will involve staying in hotels, I am doing a 5 day tour of the outback with saraha tours. They say to bring good walking shoes but not sure whether to go for a pair of Timberlands (Nellie ones as shorter) or a pair of trainer style hiking shoes like Merrell. I already have a pair of those but feel they slip on wet ground quite badly so is there anything else other people could recommend. Also, has anybody out there actaully done this tour - is it any good?
