can 7 year old sit in front of car

In Australia, once a child is 7 or older, they may sit in the front seat legally—though every safety boffin (and their crash test dummy) will tell you the back is safer.

Use an approved booster if they haven’t outgrown it, and make sure the lap‑sash belt sits on the shoulder and hips, not their neck or tummy.

If they must ride up front, slide the seat back as far as practical and keep them upright; never put a rear‑facing restraint in front of an active airbag, obviously.

Rules vary a touch by state and territory, so check the local road authority—but the gist is simple: back seat best until they properly fit an adult belt.
