Thirteen people have now been issued with infringement notices in NSW for breaching the state's lockdown rules.
One man was given two warnings on Wednesday before police found him out in public a third time "eating a kebab on a bench", NSW police said in a statement. He was fined AU$1000 (NZ$1025).
Another 12 have been issued with infringement notices - including a 28-year-old man who recently arrived in Australia from New Zealand. Currently, anyone entering Australia must self-isolate for 14 days.
NSW Police Commissioner Mick Fuller said it's important people follow the rules.
"A good rule of thumb is that if you are questioning whether you should be doing something, it is best to give it a miss.
"Treat every situation like you have the virus."
Fuller said every infringement issued was taken seriously.
"We review each fresh infringement to make sure it was issued lawfully," he said, as reported by The Sydney Morning Herald.
"Obviously I need to talk tough to get some people to turn on.
"I don't have the power to put someone in jail for six months. The same legal protections apply to people with these powers, as they do in any other powers that I have."
As of 6am Friday, Australia has 5224 cases of COVID-19 - 2389 of which are in NSW.
