The problems for years have been usually connected with overseas visitors who have never driven a large 4wd on sand. The hire companies have road pressure air int he tyres at the high end of the range too and those hire fourbies are always getting bogged...you get sick and tired of stopping to help them - I get pissed not at them abut at the hire companies. It should be legislated that you cannot hire a vehicle on that island if you are from overseas as a tourist unless all drivers do a competency course in the vehicle to be hired..the alternative and probably the best course is to make hire vehicles non existent on the island and the tourists can take a bus...it then provides a lot less environmental impact (more controlled also) and frees up the beaches and tracks for people who, generally speaking, have half an idea of what they are doing.
The problem is I think that this Govt might just shut down all 4wding on fraser unless its by tour operators and I for one would hate to see that, and would never go back.
