When i was in melbourne a few months ago i was speaking to my friend about Calder Park. He said that Bob is planning a major overhaul of both Calder and AIR.
He only knew a small amount about the AIR renovations, It will be getting digital signboards (ex calder displays), resurfacing of the whole track and some facility upgrades aswell.
He has put a huge amount of money aside for both tracks, however i feel Calder will get the majority of the money knowing the plans they have for the Melbourne facilities.
and the feeling i got from my friend (who is close to Bob) is that BJ wants to get the 2 tracks up and running to their full potential as both open track days and state level motorsports. At the moment Calder is open at least 1 day a week for free practice and bob wants to bring this sort of public access to AIR.
I will dig for some more info and let you know what i hear.
