Sydney's iconic New Year's Eve fireworks display could be cancelled this year owing to the ongoing industrial action by the Rail, Tram and Bus Union (RTBU) seeking pay rises and improvements to working conditions.

Sydney New Year’s Eve fireworks could be cancelled due to train strike, police warn - Union accuses police of scaremongering over industrial action

New Year's Eve fireworks on Sydney's harbour could be canned due to safety concerns, Australian police said on Friday. New South Wales Police Commissioner Karen Webb said she had "grave concerns" about safety given industrial action by transport unions in the city.

Sydney New Year's fireworks, one of the world's most spectacular celebrations of the calendar change, face being scrapped because of industrial action by train workers, police said Friday.

The New South Wales government has lost its latest legal challenge to stop the threat of strikes on Sydney's rail network, putting the city's showpiece New Year's Eve firework event in jeopardy.

Cancelling Australia's biggest New Year's Eve fireworks display could send businesses to the wall, but the impacts of rail network chaos are already in play.

Police Commissioner Karen Webb said she could not rule out cancelling the fireworks if 250,000 people who depend on public transport were unable to get home safely.
