Travel Tips

Fuel Stops
Always fill your tank in major towns like Charleville or Bourke. Do not rely on remote roadhouses for fuel availability.
Wildlife Awareness
Avoid driving at dawn or dusk to minimize the risk of hitting kangaroos or emus. These animals are most active during these times.
Connectivity
Download offline maps as mobile reception is non-existent on large stretches of the Mitchell Highway.
Vehicle Check
Ensure your cooling system is in top condition. Outback temperatures can stress older engines significantly.
Rest Breaks
Follow the 'Power Nap' rule. Stop every two hours for at least 15 minutes to maintain alertness.

Safety Tips

Emergency Supplies
Carry a satellite phone or a PLB if you are traveling solo. Mobile coverage is unreliable in the outback.
Road Conditions
Check the Queensland Traffic and Live Traffic NSW websites before leaving. Road closures due to flooding can occur.
Stay with Vehicle
If you break down, stay with your vehicle. It is easier for rescue services to spot a car than a person walking.
Dust Storms
If you encounter a dust storm, pull over safely, turn off your lights, and wait for visibility to improve.
