Lloyd, worst case scenario would be
Yuendumu to Billiluna. If you're doing it on a weekday you will have no issues with Diesel availability. If you are doing this on the weekend you'd better
check opening hours of both
places. There is absolutely NOTHING in the middle, some mines, that's about it. When travelling in remote outback I think you ALWAYS need to be prepared to miss a fuel stop in-case they simply don't have fuel. In your case it will be Tilmouth
Well (I've been there and he's had no diesel) and on the other side is
Halls creek. Being the paranoid person I am I had 180L in the fuel tank and another 60L on the roof (diesel) and we filled up at
Yuendumu...
