One of the more demanding tracks in remote SA. The Grade 4-5 difficulty and elevated RRI demand proper expedition preparation. Not for novice remote drivers. Distance from any services is extreme.
Recommended gear: Recovery boards, Snatch strap, Hi-lift jack, Satellite comms (mandatory), Water (20L+), Spare tyre.
The road
Postmark Track is a 12-kilometre track in the SA arid zone near the New South Wales border - one of the more demanding accessible tracks in the state. The Grade 4-5 difficulty and elevated Recovery Risk Index of 6.48 reflect both the technical sand and clay terrain and the extreme distance from any services. The landscape is a mix of mallee scrub, saltbush flats and sand ridge country transitioning toward the semi-arid plains around Broken Hill. Very few 4WD tracks penetrate this region compared to the more famous Flinders or the sealed Outback highways, which means the tracks that do exist see minimal traffic and minimal maintenance. Satellite communications are mandatory. Fuel is available in Broken Hill to the east or Renmark to the west, but distances are extreme either way. Full expedition preparation is the baseline: recovery gear, minimum 20 litres of water per person, spare tyre, and a detailed route plan lodged with someone reliable. Summer is not an option. Broken Hill across the border is one of Australia's best outback destination towns. The silver mining city has the Pro Hart gallery, an excellent city art gallery, and the Line of Lode mine site that tells the story of BHP's origins. Mutawintji National Park northeast of Broken Hill has remarkable Aboriginal rock art and gorge country that ranks among the most significant cultural sites in inland Australia.
