Seven of nine teenagers arrested in the Hunter following a police pursuit through Lake Macquarie and Newcastle this week were from the Western Sydney lockdown zone.
All nine have been fined $1000 for breaching COVID-19 public health orders - three were charged and six will be dealt with under the Young Offenders Act.
The Greater Sydney lockdown was this week extended until the end of August, with eight local government areas in the city's west and southwest deemed Coronavirus hot spots.
The teenagers were arrested after the alleged car chase on Wednesday and taken to Belmont Police Station.
A police spokesperson reiterated on Thursday that precautions are taken by officers to ensure strict health and workplace safety guidelines are being adhered to - including using face masks, gloves and sanitiser.
It comes after police spotted a Honda Civic allegedly travelling at an excessive speed on the Hunter Expressway about 11.15am on Wednesday.
Officers followed the vehicle, which allegedly reached speeds of 120km/h in a 90km/h zone.
The chase was terminated at Wallsend, but police saw the car several times in Newcastle and Lake Macquarie.
The vehicle was found dumped at Cardiff just after midday and officers soon arrested nine people who had fled the scene.
Police on Wednesday night charged a 19-year-old woman with travelling in a stolen car and breaching bail, while a 15-year-old boy was charged with driving recklessly, being involved in a police pursuit, speeding or driving in a dangerous manner, stealing a car and not giving his details to another driver after a crash.
The third person charged, a 16-year-old, faces counts of breaching bail and travelling in a stolen car.
The other six teenagers - aged between 13 and 17 - will be dealt with under the Young Offenders Act, police said.
The Young Offenders Act is a legal pathway for juveniles to be dealt with for alleged offences outside the court system, including through warnings, cautions and Youth Justice Conferencing for eligible young people.
