Australians have complained about a mysterious rumbling noise that lasts “all night” and are convinced it has nothing to do with roadworks.
North Sydney residents, particularly those in Crows Nest and St Leonards, have expressed frustrations over the “constant” and “repetitive” buzzing that many claim has been appearing on and off for years.
The noise changes from a rumbling hum to an “electronic warble” that many have dubbed “alien” and “consumer.”
A local thought it was thunder at first, but after it lasted a few days she assumed it was due to the new subway station.
‘Does anyone else hear a dull thud that comes and goes rhythmically, every few seconds?’ the woman wrote on Facebook on May 26.
North Sydney residents have vented their frustrations online over a strange humming noise heard at night.
“It lasts all night and at first we confused it with thunder or with the subway that is being built, but it is constant and has lasted for days.”
Several offered suggestions as to what the strange humming noise could be and questioned whether it was the noise of trains, water pumps, exhaust fans, airplanes or construction work.
Conspiracy theorists, however, had a “clear” answer: aliens.
Others who claimed to have heard the noise said they felt like they were “going crazy.”
‘Yes, I heard the same (sound). For us it starts around 5pm and seems to end after a few hours and has been happening for the last week,” wrote a resident on the same street.
‘The first night it happened I was looking for the sound and I noticed that I could hear it louder when I put my ear closer to the wall, this makes me think they are underground vibrations.
Residents of Crows Nest and St Leonards complained about the sound in the area mentioned above.
“I imagine tunnels would be built for the tube, so if tunnels are being built for the Warringah Highway that could be an explanation.”
Another man said: ‘The other night I thought I was going crazy trying to explain that strange earth-moving thud. I can sleep through anything, so I moved on, but I’m wondering if this is the same thing. I’ll listen to it tonight.
Another neighbor wrote: ‘I know that sound very well. I heard it last year.
This is not the first time North Sydney residents have complained about a strange humming noise. In November 2022, a man heard a “strange low-frequency hum” at 6am and had no idea what was causing it (comment on photo)
A North Sydney Council spokesperson said they are urging locals to get in touch if the problem continues.
“To investigate the noise, Council would need to receive a report from the community,” the spokesperson told Daily Mail Australia.
“If anyone has a noise pollution problem, they can contact the council, tell them the details of the problem and then we can investigate.”

In September 2021, a local man complained of a “loud, repetitive beeping” that can only be heard at night.
‘I think it comes from one of the works, but I can’t pinpoint it (it echoes!). “It rings every ten or fifteen seconds,” she wrote.

For decades, scientists have been baffled by the phenomenon known as the Bristol Hum, where thousands of people around the world have reported hearing indistinguishable sounds emanating from the sky.
The mystery even appeared in an episode of the hit American television show, The X-Files, in 1998.
The first research into the phenomenon was carried out in 1973 and examined 50 residents living in the British city of Bristol who claimed to be hearing a “mild, throbbing background noise”, often early in the morning.
Since then, thousands of people around the world have also experienced this strange sound: in the US state of New Mexico it is known as Taos Hum and in Ontario, Canada, as Windsor Hum.
Over the years, conspiracy theorists have blamed the noise on secret military experiments, alien spacecraft, and a host of other paranormal explanations.
