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.
Thermal patrols – May 2025
From Monday 19 to Friday 23 May we will be conducting thermal inspections on our transmission network.
Our aerial team will use a handheld thermal camera to identify any wear and tear on the lines and inspect all conductors and hardware on the transmission towers. We'll be looking for any abnormal thermal signatures that could impact the electricity supply.
These inspections help us provide safe and reliable electricity to our communities. The map below shows where you may see our helicopters.
