However the night was not without some trouble.
On the Central Coast, a man was killed after he was hit in the head by a firework at Budgewoi Beach.
Police believe the 52-year-old man was trying to light the firework about 3am and suffered a serious head injury.
His friends and emergency services tried to revive him but he died on the beach.
Tuggerah Lakes police Chief Inspector Col Lott said the local man was among 10 to 20 people socialising on the beach at the time.
"A group of friends were down the beach and he decided to try and light this firework and it exploded," he said.
Acting Deputy Commissioner Frank Mennilli told reporters on Sunday the firework was an old and "fairly large one" the man had for a number of years.
In a related accident, a teenager suffered serious eye injuries after a firework exploded in his face at Blue Haven on the Central Coast.
The 19-year-old was also trying to light a firework and suffered serious burns to his face at 12.20am.
Police say he will undergo vision tests over the coming days.
On Kent Street in the Sydney CBD, a 26-year-old man suffered a fractured skull after falling from the tray of a truck about 9.30pm.
He is currently in St Vincent's Hospital in a critical condition.
In Parramatta in Sydney's west, a man was seriously injured after a fight on Belmore Street.
Police say the victim, 36, and a man he knew - aged 24 - had left a party at a Brickfield Street unit when they began to argue.
The dispute turned physical and the 36-year-old was pushed to the ground. He hit his head ont he footpath and lost consciousness.
He was taken to Westmead Hospital, where he remains in a critical condition.
The 24-year-old, from Five Dock, was charged with recklessly inflicting grievous bodily harm and was granted bail to appear in court on January 10.
In another incident in Balmain overnight, a man in his late 20's died after falling or possibly jumping from a building on Darling Street.
Police were on scene, after receiving reports about someone on the rooftop, when the man fell to his death, sparking a critical incident investigation.
NSW Police Assistant Commissioner Mick Fuller said there didn't appear to be any suspicious circumstances.
"There were a number of witnesses not just police and emergency services but civilians so again there is a lot evidence to be collected over the next 24 hours," he told reporters early on Sunday morning.
Operation Talisman was a proactive policing strategy focused on crowds in the Sydney CBD with 15 arrests made throughout the night.
This was about half the arrests made during New Year's Eve 2015.
Mr Fuller said most arrests related to alcohol but he largely praised the crowd behaviour.
"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.
"They were extremely patient.
"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."
