25km/h speed limit applies:

• Between school crossing (koala crossing) when the lights are flashing as indicated by a Children's Crossing sign.
• When a child is within a school zone, which is formed between a school zone sign and end school zone sign. This applies whenever a child is on the road, footpath, median strip, or even on a bicycle including outside of school hours.
  A ‘child’ means a person less than 18 years of age, and includes a student of any age wearing a school uniform.
  A school zone is also marked with zigzag lines on the road where practicable, to show that you are approaching a school zone.
• You must not exceed 25 km/h when passing, in either direction, a school bus that has stopped for the purpose of setting down or picking up children.
