Road animals are a very real threat to Australian drivers. Much more so, than what we are used to in Europe. Numbers of wild kangaroos, wombats and emus are high, therefore the probability to meet one, balances above 100%. Because it will be more than one.
The animals are especially active and choose to cross the road around sunrise and sunset, and that's also when the change of lighting conditions is quite unfavourable to the driver. The official advice is not to drive when it's dark.
Unofficial as well.
Deciding not to listen to wise words, that's what you risk:
Something between an overgrown rat and a small bear, these animals are heavy and tough. Your car is guaranteed to be a wreck if you hit one.
High in stature, they pose an increased risk. Their body, after the impact, is travelling at a high speed through the windshield and towards a driver.
The unpredictability of their actions is also an important factor. Just a second ago they were runnig away from your car, but now speed right towards it.
They often travel in pairs. If you see one crossing the road and managed to miss it, do not cheer up. There is a big chance the second one is somewhere closeby, following its friend.
