If you've got time to burn you could check these guy's out to
http://www.australianspeedway.com/1-...intcar-videos/
Its just near a go-kart track
http://www.kartshop.com.au/
and a moto x track (sorry i don't know the website) and a drag strip

I don't follow these much so I can't tell you what's a good night to go but it may be a good time filler.
