does a 7 year old need a car seat in qld

In Queensland, the law is as clear as a sunny Aussie day: children under 7 years old must be secured in an appropriate child restraint or booster seat. So yes, a 7-year-old typically still needs a booster seat because they usually haven't reached the magical height of 145 cm to graduate to a regular seatbelt. The law aims to keep the little ankle-biters safe, not just to annoy you. Non-compliance can lead to fines and demerit points, so don’t risk it. For exact details and exceptions, check the Queensland Government’s transport site or have a gander at ServiceCentral for local advice.
