I've been lucky enough to see quite a bit of Australia and tend to book tours in areas where the terrain is quite rough and a guide is required or when I've limited time and want to make maximum use of the time I do have.
This one day discovery tour was so memorable yet simple and without the fuss. Sean is very knowledgable and is a true asset to the tourism product of WA. I booked via the visitor centre - if I had my time again I'd book direct, Sean may not get back right away but he'll respond within 24 hours as he is often in areas of limited phone coverage.
Its absolutely worth the money and ideal for those who enjoy a bit of comfort without paying a fortune.
