What's one thing you should never do in Australia?
Never say never, but hey if you want risk mitigation then...
1. Driving at night on country roads when kangaroos are hip-hopping about is probably not the best idea. Particularly in a hire car. A collision with one of these guys is highly likely and not insured!
2. If you hear a siren at the beach, you best not keep swimming. It's a shark warning.
3. Leave your fish & chips unattended - not even for a second!
Speed !!!! Never ever speed not even 1km over .
Fines are huge and there are cameras and speed traps everywhere. In Australia speed limits are low and it is very easy to lose your license . Court costs are high as are lawyers bills . Please plan on aiming to drive about 3 km per hour below posted speed limits to allow yourself some leeway for slight changes in speed. Use your cruise control often if your easily stressed while driving under such exacting conditions .
