I'd imagine T12 would be quite spectacular especially if you can see T11 from that point. 
Glad you said that!! I have already booked T12 - 13! So excited!!!
Just moved to NZ from UK last week, and taking this time to experience a new GP, (been to Silverstone 4 times before, as well as Hockenheim and Spa).
Unfortunately, I'm a McLaren fan!! 
It seems strange to see a 4 hour flight as being nearby, but after the 25 hour flight here last week it seems like a stroll in the park!!
Would love to see any other fellow auto sport guys at Melbourne! I will be by myself as my Fiancé isn't into motorsport and will be shopping in Melbourne at the time!!
Thanks,
Paul.
