NSW police will be cracking down even harder on those who choose to break COVID-19 rules as the state struggles with a record high number of infections.

NSW Police Commissioner Mick Fuller on Thursday said police were clamping down to "get us out of lockdown sooner" and made a formal request to the Federal Government for assistance from the Australian Defence Force (ADF).

He stated that if more local government areas that were of concern popped up, he would call in help from the army. Hours later he asked for 300 ADF personnel to boost the operational capacity of NSW Police.

The fine for not wearing a mask has also been increased from $200 to $500 and Commissioner Fuller warned there would be fewer warnings issued and more enforcement.
