So it seems that corrugations are a common denominator pretty much everywhere (although those were pretty mild). What I think is different in Oz are the distances involved. We can see hundreds of km with barely a break.
Another pic, this time from the Canning Stock Route.
That is the Military coming up behind us. They can not replicate this stuff with test tracks. They are in 6x6 Mercedes G Waggons.
And another short video clip...The Canning is about 2,000km and lots of it is like this.
