We own and operate Victoria’s electricity transmission network and one of the five distribution networks.
Each year our Aerial Operations Program inspects around 40,000 poles on our electricity network from the air.
We use specialised helicopters and crew to thoroughly inspect overhead powerlines and poles to make sure the electricity supply across the AusNet distribution network remains safe and reliable.
Why we use helicopters
Helicopters significantly reduce the time taken to inspect an area. They allow a bird’s-eye view for us to identify, monitor and repair any wear and tear or potential risks to supply, such as deterioration on the topside of poles.
We're aware that noise from helicopters can present a risk to some livestock. That's why our specialised pilots remain alert for livestock and, where possible, change course to avoid unsettling animals.
Playing a vital role in keeping communities safe
Our aerial team also provides rapid response to assess damage and resolve any faults/outages that occur on the network after a severe weather event, such as storms, floods, or bushfires.
LiDAR Survey – August/September 2025
From Monday 25 August to Monday 15 September, we will be conducting an Aerial LiDAR Survey on our Transmission network in a fixed-wing aircraft.
LiDAR stands for Light Detection and Ranging, and the images we collect will help us find any trees or foliage that is too close to the powerlines. This is all part of our annual vegetation management program, designed to keep the easements clear and make sure high-risk trees are identified. After we analyse this data, we'll work on trimming or removing vegetation throughout the year. These inspections help us provide safe and reliable electricity to our communities. We will be flying at 1200ft, the map below shows where you may see our aircraft.
