Dave/Greg, I have just seen this article and your right Dave, this has been discussed before, but I can't find it either.
Getting back to the around oz trip. I remember reading an article about it in a bike mag, I think it was the old AMCN ( Australian motorcycle news) in the late 70's or early 80's. Your right Greg, It was too policemen or ex policemen, riding Z1300's and they did it in under 7 days. I have a feeling, but I may be wrong, one of them was Warwick Shuberg founder of 'Stay Upright.'

Cheers Ben
