Hi Peter & Kieran
I've only been using the site for a month or so and have never watched any Australian activity (actually, didn't know it existed) as I presumed it was just based around Europe.
Another great site I was told about is
http://casper.frontier.nl/eham/ which is centred on Amsterdam with more cities to follow. It doesn't show the regos of aircraft but is still very good.
Cheers
Bob
