Vegetation management

Trees, shrubs and other vegetation enhance our lifestyles. However, vegetation touching powerlines is a proven risk to public safety and one of the main causes of power supply problems.

Management and maintenance

Effective management and maintenance of vegetation around powerlines is essential for public safety and reliability of electricity supply. We employ contractors for tree trimming throughout Queensland, the Torres Strait Islands and Northern New South Wales.

Tree trimming is done on a cycle based on plant growth rates. This is predicted using scientific information from satellite imagery, high resolution aerial imagery, and local knowledge.

We have also partnered with Fugro ROAMES to improve the efficiency of our vegetation program. LiDAR technology helps us identify and target vegetation that grows into our clearance profile.

Trimming is carried out by trained professionals in accordance with Australian Standard AS4373 Pruning of Amenity Trees, to ensure we adhere to legislative requirements.

Our Vegetation Management Strategy (PDF 574.1 kb) details how we manage vegetation that may interfere with the operation or safety of our powerlines.

Community awareness

Through community awareness programs, powerline friendly trees are now easier to identify and purchase through your local garden nursery.

Many schools have benefited from biodiversity assessments and plantings and most Queensland Local Council areas have recommended species lists for planting near powerlines.

Planting the wrong plant near powerlines may eventually cause an increase to the cost of electricity supply and presents an unnecessary safety risk. It may also increase the damage caused by cyclones and storms.

Research and development

Our vegetation management techniques have benefited from research and development through flora and fauna surveys and raising awareness of endangered and vulnerable species.

We aim to promote low growing species wherever possible, to minimise vegetation impacts to powerlines and maximise biodiversity and habitat retention in powerline easements.


We are committed to managing our obligations under the Biosecurity Act 2014 (the Act) and the biosecurity risk that our network activities may pose to primary producers and other stakeholders.

To meet our obligations under the Act, we have a range of measures integrated into our normal work procedures to help preserve our biodiversity, protecting our economy, environment and the community.

You can read more about these measures on our Biosecurity webpage and Land Access Protocol Fact Sheet (PDF 1.2 mb).
