Stone is one of the worst movies ever made: inept direction; bad (funny) dialog, low production expertise and values, bad editing and endless boring sequences of motorcycles as if a bike on a road is interesting cinema. Yes, there is a big stunt, but that does not make a film.
The movie is a boring and unintentionally funny, ridiculous counter culture trip that owes much to Easy Rider without a Hopper or Nicholson.
Stone's special sentimental place in Australia must be due to the audience's thrill at seeing their own on film. Some movies should be banned to save a country total humiliation - and Stone is one of them.
