Protesters warned to feel the 'full force of the law' if they attend

NSW Police Minister David Elliott has warned anyone who plans to attend an illegal protest in Sydney this weekend will feel the "full force of the law".

He has urged people not to put their family, friends, and loved ones at risk by gathering in large groups.

"The message to the people of NSW is stay indoors," Mr Elliott said.

"If you want to go out tomorrow and endanger the lives of everyone you love and extend this lockdown go ahead and meet the full force of the law.

"It's not rocket science… you go outside you risk the prolonging of the lockdown."

NSW Police Deputy Commissioner Mal Lanyon echoed Mr Elliott, saying gatherings need to be capped at two people.

"If you intend in attending a protest, we will take action at the time.

"If not we will continue to investigate and take action against you," he added.

Deputy Commissioner Lanyon said more than 60 charges and 300 infringements were handed out since the last protest.

"Those people thought that they could protest unlawfully and have since found out that they can't."
