i believe with the Kilcoy track that the car club that was organising it (was it the MG Historical car club or something) are still looking at going ahead with it, however, it may not be at the same location.
i'm all for seeing lakeside re-opened, however it is an insurance nightmare for whoever takes it over, due to the track having little to no run-off areas in places, and the track starting to degrade due to little to no use over the last 4 or 5 years.
i was actually out there a while back for a skidpan day, probably about a year or so after the complex had closed (there's a small skidpan at the back of the track) and even then, you could see that the place was starting to fall apart due to lack of upkeep on the council's behalf.
don't get me wrong, i want to see it opened up again, however i can see it being a case of it may reopen, then the first time someone has a bit of an intimate encounter with the armco, they'll shut the place down again.
