At the height of the protest 14 people, none of them wearing masks, stood in silence on Byng Street.

Organiser Debbie Thornton said it was part of an Australia and New Zealand-wide protest against "government corruption". She said they were calling on all levels of government to resign and for fresh elections to be called.

However, after about an hour, police officers arrived and began questioning the group. Four people were placed in police vans while others left the scene after speaking to police.

Central West Police District Chief Inspector Dave Harvey said the charges including failing to wear a face covering (five people), failing to comply with a direction notice (six people), failing to move on as directed (one person) and offensive language (one person).

He said they would be issued with infringement notices. Chief Inspector Harvey said the people were all from Orange.

Assistant Commissioner Geoff McKechnie said there were protests across the region.

"Small numbers of people [were] totally disregarding the safety of their communities, their own safety, the safety of the police officers that are dealing with them," he said.

"Mindless behaviour by people who aren't going to achieve anything. What is it going to achieve in the long run? Please, wear the mask, stay home and abide by those orders."

Before the protest Ms Thornton said she was not against COVID vaccinations or wearing masks in public but instead was "pro-choice".

She and other people at the protest said they were not aligned to any political party.

Ms Thornton said they wanted to have a silent protest meeting.

"No noise, no placards, no nothing, " Ms Thornton said.

She and other people at the rally said they were concerned about the COVID lockdown, "corruption" in big business, human rights and the spread of 5G.

They said they wanted to see the 'truth' revealed about government and business links.
