Les meilleurs tronçons d'Australie

Sealed tertiary through the Victorian High Country near Mansfield. Curviness 257, elevation 110m per kilometre, score 9.84 across consecutive segments. Low traffic and no destination - you come to Yabba Road for the road, not what is at the end of it.

Outer Melbourne fringe back road between Hurstbridge and Arthurs Creek. Curviness 555, elevation 179m per kilometre - the tightest combination in the Yarra Ranges. Almost no traffic because the only reason to be here is the road itself.

Sealed tertiary climbing east of Dargo into the Victorian High Plains. Curviness 518, elevation 136m per kilometre, score 9.84. Closes in winter snow - in spring and autumn this is one of the sharpest alpine climbs in the state.

The highest curviness index in NSW at 757. Sealed tertiary on the NSW-QLD border near Kyogle, climbing 165m per kilometre through range country. No trucks, no shortcuts - Lions Road has no other purpose.
