Well, in the Australian outback you often have graded roads:

These allow speeds of 80km/h so tertiary really isn't a bad choice.

We're having this like discussion with the AND data for NL. They
distriguish between the road type (what OSM has) and the "functional
road class", where it is in the scheme of routing. Basically a road
may be unsealed but can simultaneously be the main road for hundreds
of kilometres. The current OSM model can't handle this very well.

Have a nice day,
