Every year, around 5,000 children in Australia end up being trapped in cars during hot weather.
While the vast majority of them end up being rescued, an unfortunate few end up in hospital.
In the worst cases, the children can end up losing their lives.
Kidsafe Victoria has launched a campaign to try to prevent children becoming trapped in cars.
As Australia's increasingly hot summer continues, parents are being warned it is never safe to leave a child alone in a car.
Dr Cathy McAdam, the Head of General Paediatrics at Monash Children's Hospital in Melbourne, says the danger cannot be underestimated.
