Four people were arrested and eight fines issued by police after an anti-lockdown protest outside Wyong Council Chambers on August 31.
During a similar protest at Gosford, two were arrested and 10 fines issued.
Each of the $3,000 fines were for unlawfully participating in an outdoor public gathering, in contravention of the COVID Public Health Orders.
Those arrested could face a fine of $11,000 or up to six months in jail.
Inquiries into the incidents were continuing and police expected more fines to be issued, including for failing to comply with a self-isolation direction at $5,000.
The unauthorised demonstrations were part of co-ordinated anti-lockdown protests held at 79 sites across NSW, primarily targeting council chambers.
Parliamentary Secretary for Central Coast, Adam Crouch, said he had been advised that about 40 people attended the protest at Wyong and about the same number at Gosford.
“I am disgusted that a minority of people on the Central Coast have risked the health and safety of themselves, their families and their wider community by choosing to protest,” he said.
“These actions are incredibly selfish and we can only hope that no COVID-19 transmission occurred among the protestors and Police officers.”
Police continue to appeal to the community to report suspected breaches of any public health order or behaviour which could impact on the health and safety of the community by contacting Crime Stoppers on 1800 333 000.
