I think Thredbo, the track needs to be slightly changed more challenging I think. Having a 6:15minute (pro times) time track would be different to what the normal world cup 3-5minutes tracks are like, I would be voting Thredbo or Mt Buller, cause of a chairlift, the hill is nice, there is lots of parking and accommodation and facilities, despite what people complain if you rode it for the first time again as a pro, it would a great track I think, there is plenty of space for a village down below the chairlift on the mulch, and I have always liked Thredbo it feels like ma home track, just good vibes there. Not as close as Canberra but I think it would suite a world cup more, if they spent the money spent on Mt Stromlo making Thredbo better.....it could be easily a world cup park, but no avail national parks.
