car seat for 7 year old australia

For a 7‑year‑old in Australia, the legal allowance is a booster seat used with a lap‑sash belt or an adult seatbelt if it fits properly; best practice is to keep them in a booster until the belt sits just right.

Look for restraints complying with AS/NZS 1754, follow the height‑marker guidance, and aim for good belt fit across the shoulder and low on the hips (many kids need a booster until roughly 145 cm tall). A high‑back booster with side protection and a top tether (if the model requires it) keeps things neat and safe. Check your state road authority for any local twists, and install it like you mean it—tight, level, and not wobbling like a shopping trolley.
