Firework fans are being warned to leave the pyrotechnics to the professionals this New Year's Eve.
SafeWork NSW warned on Tuesday backyard firework displays were banned and people caught using explosives without a SafeWork licence could be fined.
"Most people want to start 2023 with a bang and SafeWork NSW wants to ensure all firework events are compliant and being operated in a safe manner," SafeWork NSW head John Tansey said.
It comes three weeks after nine people were injured at a family Christmas carol event on Sydney's northern beaches when a firework ricocheted into the crowd.
While the event at the Allambie Heights Oval was endorsed by council, the incident showed "exactly how dangerous these explosives can be," Mr Tansey said.
"Fireworks are dangerous explosives and can cause devastating injuries if not handled correctly or set off by a professional," he said.
Anyone caught selling, buying and setting off fireworks without a licence faces fines of up to $27,500 and 12 months in prison in NSW.
Most other states and territories also restrict the possession and use of fireworks solely to licensed pyrotechnicians.
The exception is the Top End, where for one day Territorians can buy and ignite fireworks for Territory Day celebrations on July 1.
