Two men have died in separate incidents on New Year's Eve after being struck by fireworks.

In NSW, a man was killed at Budgewoi, on the NSW Central Coast, just before 3am after he was struck by a firework, police said.

The 52-year-old man man sustained a serious head injury and despite the efforts of friends and emergency services at the scene, he could not be revived.

In Victoria, a man in his 40s was also reportedly killed by an exploding firecracker.

Paramedics were called to assist the man after a report he was seriously injured by a firecracker, east of Melbourne, about 9.45pm on New Year's Eve.

Sadly, the man, from Hollands Landing in Gippsland, died at the scene.

Earlier, another man in his 20s died after police were called to Balmain in NSW following reports of someone on top of a building at about 9.40pm.

Police and emergency services rushed to the scene but the man fell and died.

Two other people are said to be critical in hospital after other misadventures on NYE in NSW.

It was a massive night for authorities, with more than 2000 officers deployed for Operation Talisman -- NYE's high-visibility policing strategy.

"Police are pleased with overall crowd behaviour, with only a small number of revellers arrested and charged for anti-social behaviour and drug-related offences," police said in a statement.

NSW Police Assistant Commissioner Mick Fuller told Fairfax Media most arrests related to alcohol.

"Particularly when we reach peak crowd capacity at 9pm and we had to close a number of the key venues there was still many people on the street," he said.

"From our perspective we really feel the community heeded our warnings. They planned the night, they have acted in good faith and really seen 2016 out in a positive way."
