It’s official: hoons have turned Milsons Point, Kirribilli and Blues Point into their nightly playground – and last week’s police blitz proves the problem is only getting worse.

On 29 August, Northern Sydney Sector Highway Patrol teamed up with Transport for NSW inspectors to target the flood of noisy, modified cars that roar through the lower north shore after dark.

A temporary inspection station was set up on Burton Street, where officers spent hours pulling over vehicles with illegally tweaked engines, booming exhausts and blinding lights.

By the end of the night, 43 cars had been stopped, with 11 sent straight to the inspection station. Police report that a total of 50 separate defects were identified.

Drivers were slapped with 34 infringement notices, and four vehicles were branded with a dreaded yellow sticker – meaning they could only be driven home and must be fixed before returning to the road.

NSW Police say it’s part of a coordinated push to restore peace for residents who’ve endured months of late-night revving and burnout stunts around the harbour foreshore.

“All motor vehicles that travel on NSW roads are required to meet strict design and registration standards to ensure they are roadworthy and safe,” Transport for NSW Executive Director Road Safety Regulation, Duncan Lucas, said.

“Modifications to increase ride height and accommodate oversize tyres can affect braking performance, steering response and stability, change handling behaviour, affect steering response, create directional instability, and increase chances of rollover.”

Locals, meanwhile, say the nightly noise has reached unbearable levels, with drivers converging on carparks and streets after dark. The scenes, reminiscent of a Fast and Furious film, have sparked scores of complaints to police and the Council in recent months.

Authorities warn the August crackdown won’t be a one-off. NSW Police and TfNSW confirm more surprise blitzes are coming, with officers determined to send a clear message to thrill-seekers: the lower north shore is not a racetrack.
