Not many great drives left in Australia now due to the speed wowsers, safety nannies and over-arching police state attitude to traffic management and revenue collection. The Great Ocean Road west from Melbourne is pretty good. The Nullabor used to be great for a sort of Cannonball Run, but a lot of it is pretty boring scenery-wise. I recall breaking the sound barrier there a few times "commuting" back and forth in my Maserati back in the 70's, when sensible cops used to ignore a good car being driven fast but well, or if they stopped you they would just want to look at and maybe sit in the car. One policeman actually wheeled into a layby in his candy-car where I was stopped to camp for the night to ask if I was OK and, surprisingly, if I was armed. I said "yes". He said "good" and when I asked why he was inquiring about that, went on to explain about some guy terrorising the roadside car-parks and had beaten up some guy and his girlfriend the previous night before robbing them. Sadly, not much of that sort of practical attitude, respect and common-sense around now. The younger people on this site will never know what it was like "back then", unfortunately. Back then our cars drank fuel like crazy but you could run Alice to Darwin or the Nullarbor flat out to 250 or more if you could afford the juice which was a lot cheaper then too. Now we have faster, safer, better handling and more economical cars, but we are forced to drive at snail's pace and die of boredom and often boredom induced inattention.
NZ is better, and has better formed roads with proper cambers, fewer corrugations and better views, but legislatively is becoming like I describe above in this country.
Argentina has some great roads, and you can sit on 140 or more for ages, but the surface quality can vary quite suddenly. The Gendarmes leave you alone there, too. Chilean roads are better as the country is wealthier and it is common to be passed on the autopista by locals while sitting on 150!!
Here we can but dream of it now.
