Seeing the Simpson Desert as a true remote wilderness area, that has seen less than a hand full of people ever venture into the true heart of the Worlds largest parallel dunes system. See Aboriginal stone chippings and grinding stones, left where they were abandoned hundreds of years ago. See dramatic changes in desert vegetation and dune shape and construction as you slowly crawl across the desert.

MUST READ: You are strongly encouraged to read the following articles prepared by the knowledge experts at ExplorOz for your safety and preparation before undertaking any published ExplorOz Trek - Outback Safety, Outback Driving Tips, Outback Communications, and Vehicle Setup for the Outback.


Please refer to Road Reports published by the local shire and/or main roads for the area you intend to visit. Road/Track conditions can change significantly after weather events. Travellers must be responsible for their own research on current conditions and track suitability.
This trip should only be undertaken by EXPERIENCED outback desert travellers ONLY! Because of the very remote nature of the area to be travelled, trip leaders must be very competent in GPS navigation, as there are no tracks to follow for over 90% of the trip, being pure off road travel at a very slow pace.

All supplies of food, water and fuel, must be taken before the trip is started. Do not under estimate your fuel and water usage, as there are no back up supplies to be obtained along the way. Any sort of vehicle recovery would be very difficult and extremely expensive. As well as vehicle preparation, participants’ health issues must also be catered for. Visit your local GP prior to the trip and take a selection of medications that may be needed for such a remote area.

With the nature of many of the dunes to be crossed, I would also highly recommend using the GPS in conjunction with a moving map programme with EOTopo maps for real time moving mapping. There will be many times that GPS navigation will not be enough, and the moving map will help you to navigate safely around some of the larger dunes that will be impossible to cross. We recommend the ExplorOz Traveller app with Premium Offline EOTopo maps, which is available to use on Windows 10 devices, Android phones & tablets, as well as Apple iPads and iPhones.

First and second gear low range is the usual gearing, showing how slow your progress will be. Also recommend a minimum of 2 GPS units and 2 computers, as well as a standard compass in the group, in case of GPS failures.

Vehicles must be in first class condition, as well as tyres, and suspension. Make sure that you carry extra tyre plugs and tubes, as you will be guaranteed many punctures, mostly side wall type. It will be the first few vehicles in the group that take the lead that are going to be guaranteed punctures, clearing the track for the following vehicles.

Your vehicle will need to be extensively prepared for remote area travel, with all fuel, water, food and vehicle repair equipment and spare parts.
