Hello, my children haven't made reservations. Can I add them when picking up the car ?

In Australia, especially in the sparsely populated Western Australia, it is rare to encounter traffic police. You should not have children sitting in the front seat to avoid being caught, but safety comes first. During the eight days in Western Australia, I did not encounter a single police officer. When returning the car in Perth, I saw a child safety seat abandoned in the parking lot, which was indeed a helpless act. Renting a seat is not cheap, so you can bring your own.
