EDIT: Decided to ditch the back-to-back season start due to the fact that we are likely to start our TM championship on the 15th. So the season now starts on the 22nd of January and ends on the 23rd of September, which should be just about where F1 2012 releases.  

EDIT 2: Due to some scheduling conflicts with the TM GPs the season has been pushed forward a week after the Good Friday race, so there will be a race on Sunday the 15th of April and for every 2 weeks thereafter, ending one week earlier on the 16th of September. 

EDIT 3: Melbourne race in Saturday. This is due to the real Australian F1 Grand Prix being held the next weekend with not only a potential clash taking place but with a few of us Aussies likely to be at the race itself.

EDIT 4: Silverstone race on Friday. (This is due to Easter being held that weekend. This race will be on Good Friday evening for Aussies and Good Friday morning for Europeans, and due to it being a public holiday with the weekend afterward most people should be right to attend this one.)
