Do worry about the magpies
The magpies are out to get you for roughly six weeks every spring. These birds aren't joking when they say they'll swoop down on any unwary walker or biker. Even if you have suspicions, you are almost certainly doomed.
Magpie Alert is a service that gives a live map of all magpie attack locations in Australia. It may appear to be a handy tool for determining which streets to avoid, but it will most likely make you want to stay inside. Male magpies will fly up to 80 meters away and dive bomb people. Although it may appear amusing, their beaks may be quite painful.
The best advise for cyclists is to decorate their helmets with cable ties or googly eyes to make them seem stupid. Magpies have been a protected species in Australia since 1992, thus pedestrians are recommended to carry a stick, although they should not swing too violently. This is definitely one of the top things about Australia You Should Know before traveling to this country.
