Braad, at the Melbourne GP there are big screens virtually everywhere, so I will have to disagree with you on that.
Yes, I am going to the GP - Brabham Grandstand ( I have my tickets).
As for F1 at Bathurst - wouldn't work. Heres why:
1. Facilities suck. Despite all the changes and shit they've done, it still is insufficient for F1. Besides, there are much better facilitated tracks in Europe which they would use.
2. Track doesn't suit F1. While it provides some good v8 racing (v8's suck), the dynamics of the track aren't suitable. For example, the right-angled corners (1st and last corner - correct me if I'm wrong) are very much hated in F1. In the '80's, many of the North American grand prix tracks used these 90 degree corners (ie Detroit) and the drivers and fans hated them.
3. You may say "the '80's was a long time ago" but the fact is that today its alla bout money. Now think, why would Bernie Ecclestone take the this multi-billion dollar circus to a small hick town like Bathurst when he can take it established Metropoles such as Instanbul or Moscow.
