A golf club has been seized after dozens of cars were found with smashed windows in a residential street overnight.

Police say around 30 cars were found damaged at Penshurst in Sydney's south.

Officers were called to Kuroki Street about 3:00am on Sunday after residents said they were woken up by a loud noise.

"We got car crews out there early this morning and approached members of the public before they were able to find the vehicle themselves," Acting Inspector Corry De Gennaro told the ABC.

Cars in the nearby Judd Street, Alexandria Street and Laycock Road were also found damaged.

Max Healy's car was damaged and he says what unfolded is unsettling for everyone in the street.

"I don't know where I'm meant to get a window for this car anymore, they are becoming scarcer and scarcer," he said.

As well as the golf club, forensic officers seized several other items, including glass bottles.

They are investigating if the damage was linked to another vandal attack on cars in the same area a couple of weeks prior.

Police said they viewed the offence seriously.

"[This is] senseless and one that affects a persons quality of life," Acting Inspector De Gennaro said.

"We had last week someone spraying car doors as well," Mr Healy told the ABC.

"So there is someone bad in our area - we need to get rid of them."
