Why do I need to keep trees away from powerlines?

Trees or branches touching powerlines are one of the main causes of power interruptions and may cause fires and/or other serious accidents.

We encourage the planting of the right tree in the right place. Unfortunately, many trees are planted, or have naturally grown, too close to powerlines and need to be trimmed.

Failing to trim your trees can cause power failures, bushfires and serious accidents. In unusual circumstances, trees may even become ‘live’ when they come into contact with powerlines, posing a serious safety risk.
