Windang's Sarah Good, aged 20, and Warilla's Kaileb Lamelza, 18, were granted bail in Wollongong Local Court on Thursday after Magistrate Claire Girotto labelled their alleged behaviour "horrendous" and "reprehensible".

The pair have been charged with 65 counts of destroy or damage property each.

Police will allege Good drove Lamelza while he lent out and used a hockey stick to smash the windows and mirrors of more than 22 cars parked along residential streets in Lake Illawarra, Mount Warrigal, Oak Flats, Barrack Heights and Barrack Point between July 16 and 17.

Police will allege the pair damaged another 22 cars in an identical manner in Kiama, Shell Cove and Jamberoo on July 24 and 25, with 16 more vehicles smashed in the Nowra area on the same night.

CCTV footage depicting a suspicious vehicle, a Mitsubishi Lancer, was obtained and distributed to police patrols.

Early Wednesday morning, police were patrolling the Barrack Heights area after more reports of damaged vehicles when they stopped a Mitsubishi Lancer, driven by Good, matching the description of the suspicious car.

A 14-year-old boy was in the front seat, with Lamelza in the back along with a 19-year-old woman. A wooden hockey stick was found next to Lamelza and broken glass was on the floor.

All four were arrested and taken to Lake Illawarra Police station before the younger boy was released to be dealt with under the Young Offenders Act while the 19-year-old woman was released.

Lamelza was interviewed and alleged admitted to damaging the vehicles because it was a "fun thing to do".

"He admitted to 31 reported incidents. He appeared disinterested and showed no remorse," the court documents said. "He would use the hockey stick, lean out of the moving Lancer and smash parked vehicles for fun".

Meanwhile, police said Good "smirked" and did not show any remorse when told of the financial impact on victims.

Magistrate Claire Girotto said the pair's alleged actions were "serious" and "mindless" before releasing them due to their lack of criminal history and young ages.

They must remain at home unless in the company of their parents and need to report to police weekly. Lamelza must not drink alcohol or take drugs.

Their cases have been adjourned to August 13.
