booster seat for 10 year old australia

For a 10-year-old in Australia, the smart move is usually a high-back booster until they pass the five-step seatbelt test and are roughly 145 cm tall.

Legally, after age 7 they may use either an approved booster or an adult seatbelt, but only if the belt fits properly—lap belt low on the hips and shoulder belt across the chest, not the neck.

Look for AS/NZS 1754 compliance, shoulder-height markers, a lap-sash belt routing with a proper belt guide, and a top tether where the model requires it; some boosters add ISOFIX-style lower attachments to steady the seat, but the child is restrained by the vehicle belt.

Keep them in the rear seat, avoid second-hand seats with unknown history, and check your state road authority for the exact rules—nothing ruins a school run like a fine and a sore collarbone.
