Primary school pupils are encouraged to walk to school with their parents, siblings or friends for National Walk Safely to School day (Friday, May 18).
The community initiative aims to raise awareness of health, road safety, transport and environmental benefits that regular walking can provide.
It also positively influences cognitive and academic performance.
The annual event, now in its 19th year, hopes to combat rising obesity in children.
Research shows that one in four children in Australia are overweight or obese, and it is expected that numbers will reach one in three by 2020.
At least an hour of physical activity daily is recommended.
The event was also designed to reduce car dependency and inspire families to reduce dangerous traffic congestion around schools.
