The pair managed to leave the centre’s playground through the fire exit gates into the car park.
They then crossed Pioneer Highway, a four-lane road, before being found in the car park of a shopping centre 300 metres down the road.
In a letter sent to parents, centre owners Simon and Jane Pervan said the children opened the gates by one child unlatching the ground bolts and the other child getting a leg-up on the perspex to reach the two bolts at the top.
Smart kids, working out how to do that by working together. I wonder how old they were? Amazing how inventive some kids can be.
