Quote: I was wondering, just what, specifically, are these 'harsh Aussie conditions'

It gets much colder on Europe, the north part of the US, Canada & in Siberia, & it's much hotter in the middle east & other equatorial countries.

It's much wetter in most other places in the world since Australia is supposed to be the driest continent, [but not the driest country] & the legendary fine dust that Australia is infamous for is awfully hard to find in the major population centers where about 85% of all new cars are sold in Australia.

Africa & many other countries have much rougher roads too, so just what harsh conditions do you mean?
