Yep, Darwin to Adelaide is a fair hike with little in between but it's a good run, good roads and high speed limits so it doesn't take long. It's only just over 3,000km so it's done in no time. 😂
Seriously though, it's a great drive and there's some cool spots along the way. I hope y'all get to do it sometime. If you see a sign that says, Wolf Creek don't go there.
