Hosted by the MG car club, which runs the hillclimb track, this was another round in the state hillclimb championships (they alternate between this track and the noosa hillclimb i believe). open to essentially all cars, divided into classes, with some very fast open wheelers, a few limited use-plated subaru's and the like.
these are fairly regular (cheap to enter and cheap for the organisers to run) with a wide variety of cars, some home built and many i don't recognise older, smaller/lighter cars are favoured.
some people really go hard...some of the datsun's end up on two wheels exiting the corners.
