what age can a child sit in front seat in australia

Short answer: if your car has two or more rows, under 4 must stay in the back; 4 to under 7 stay in the back unless every rear seat is already filled by kids under 7; 7 and up may ride up front (though the back is safer).

In single-row vehicles (utes, vans), a properly fitted, approved child restraint is required in the front; mind the airbag and your state’s exact rules.

Use the right restraint for age/size—rearward/forward-facing seats then boosters—because the constable and physics both insist.

Laws are nationally consistent but enforced by states, so double-check your local road authority before you shuffle the booster for a road trip.
