Locals asleep at school, 'walking around like zombies' due to new 24/7 airport

Families living in the shadow of the new Western Sydney International Airport say they are only getting a few hours' sleep since it opened for overnight cargo flights.

Promised noise mitigation works have not been done by the federal government.

Prime Minister Anthony Albanese has been invited to spend the night with locals, who say they are "tired all the time".

The prime minister has been invited to stay the night at the homes of families who say life next to the new 24/7 Western Sydney International Airport (WSI) has been unbearable.

Loud noise from planes flying over their homes at all hours of the night is disrupting their sleep, work and lives, said those living within 2 kilometres of the runway, as it can be revealed the federal government's promised noise insulation has failed to be delivered.

One month after the opening of the airport, Carolyn Wong and her daughter Katherine found themselves forced to consider abandoning their family's Luddenham home of 70 years.

"I grew up here. My parents built the place in the early '50s," she said.

Katherine Wong said the lack of sleep due to constant noise from planes taking off and landing during the night had her in tears.

"It has been absolutely horrible. I've not been able to sleep a full night in my own bed," she said.

"It's so unsustainable. I'm tired and cranky all the time. I can't do my work properly. I can't be a good family member.

"As for [Prime Minister Anthony] Albanese and [Transport Minister] Catherine King, I'd invite them to come spend a night in my home and see what they think."

A WSI spokesperson said that since opening to cargo flights on July 27, the airport had supported an average of 11 aircraft — or 22 take-offs and landings — four nights a week between about 8pm and 5:30am Monday to Thursday.

Between 11pm Monday and 5am Tuesday, 14 flights took off and landed at the airport, with one arriving from Brisbane at 11:25pm before 12 planes came and went, before another flight departed for Brisbane at 4:35am.

Katherine Wong said the lack of sleep had also affected her work as a project manager who has to travel long distances for work.
