More than once a rogue GPS decision has directed my vehicle down an Australian road only an experienced 4WD group should attempt. The significance grows when you’re 300km from the nearest settlement.

It’s a big country, and mostly empty.

Gut feeling - Google Maps and HERE Maps know that. You could send the route to those maps. Red globe in right top corner of the map.

But here come their restrictions. Google Maps don't route many waypoints. HERE WeGo don't know places names, often around Alice Springs.

Is it difficult to do both? And yeah type of road is a huge factor in outback Australia. Corrugated unsealed roads destroy anything short of hardened touring rigs.

If this road info is in OSM, we will take it. Also you could send the route to Google Maps or HERE Maps. Notice red globe icon in the right top corner of the map, in opened trip plan. Click it, send to Google Maps, then send to your phone from them. Navigate using them. Could be possible to split the roads.
