Australia is huge and the distances to other places are big, even from our house to school was more than half an hour. You really need a driving license to be able to go to shopping malls for instance.
Nonetheless, be aware that if you have a driving license from another country, you need to do the exam in Australia to get an Australian driving license. You are only allowed to drive with your driving license from another country for a couple of months. In Australia, they drive left and from the age of 16, you as a parent are allowed to teach your children.
Every time when we were at the shopping center we made a photo of where we parked the car, as it is that huge and easy to lose the car.
Temperature
In summer the temperature can go above 40 degrees Celcius, which means it is very important to protect yourself from the sun. For instance, wear a hat, use 30+ sunscreen, and from 11:00 – 14:00 hours, it is wise not to go in the sun. Besides that, as the summers are so hot, it is nice to have a pool in the garden.
