1. If you pass a cop in the oncoming lane, flash your headlights twice to warn others.
2. If you are in a slow vehicle and a truck overtakes you at night, flicker the highbeam to let the truck know they can pull back in.
   2a. Trucks signal “thank you” to this by indicating left to pull back in, then blinker right, then left again.
3. If you overtake someone, don’t slow down after you do. That’s a dick move.
4.  If you are going too slowly, don’t suddenly speed up in the overtake zone, let others pass you douchebag
5. Always overtake ‘L’ platers… it’s the law. (Not really)
6. If someone is tailgating you, slow down even more and smile in the rear view mirror.
7. In rural australia, whoever has the most & biggest antennas and bumper stickers has right of way.
8. Never swerve for animals. We have plenty of spare kangaroos but only one you.
9. Drive 5-10% over the speed limit at all times otherwise you will slow down everyone else. Especially if you live in Sydney or Brisbane.
10. Two revs of the engine at pole position at a red light commits you to an impromptu drag race.

DISCLAIMER : Some of these things aren’t strictly law, or legal, but they are the unwritten Australian road rules. Well, technically they are written now. It’s the Australian way.

(Interestingly, a US Judge found that warning others about police with your headlines was a protected form of free speech! We don’t have free speech in Australia, but we also don’t have a law that prohibits this practice. What you can get fined with is unnecessarily using high beams for 1 demerit point, or unnecessarily flashing headlights for a small fine and no demerits. So don’t use your high beams when you flash, fellow citizen!)
