Not speeding related, but still useful advice: Don't turn left into Park St in Sydney city if you're heading south along George St- The bit of Park St in between George St and Pitt St eastbound has been turned into one big bus-lane, and the police have been waiting next to the kerb lately to catch people (you won't see them until you've already made most of the turn, then you're toast; $238 and 3 points). You can bet they'll get a few hectik-lappers on saturday nights with this one.
