Helicopters will be buzzing overhead next week as Ausgrid conducts aerial thermal patrols of powerlines as part of ongoing network maintenance.
From Tuesday, August 31 the helicopters will fly close to overhead powerlines between 7:30am and 5pm and residents are warned the noise could startle livestock or pets.
The Ausgrid aerial patrols will be conducted across Ourimbah, Kangy Angy, Berkeley Vale, Tuggerah, Alison, Jilliby, Wyee, Wyee Point and Mannering Park.
Overhead patrols will also be held at Somersby, Narara and West Gosford.
They are due to be completed by Friday, September 3.
