It comes as hundreds of thousands of school students around the world will strike for climate justice on Friday 25 March.
"Students are striking because they are terrified of the future they are inheriting and horrified by the unequal implications for others," Dr Blanche Verlie, a climate justice expert in the Sydney Environment Institute at the University of Sydney, said.
The NSW Government vowed to crackdown on unauthorised protestors who disrupt traffic.
The Roads Amendment Regulation 2022 will be made to make it an offence to disrupt any bridge or tunnel across Greater Sydney.
The regulation is made under section 144G of the Roads Act 1993, but currently only applies to disruption on the Sydney Harbour Bridge.
Section 144G carries a maximum penalty of 200 penalty units ($22,000) or imprisonment for two years, or both.
