Sydney will have an extra fireworks show over the harbour on New Year's Eve.
Producer Aneurin Coffey said a pyrotechnics display would be held at 10.30pm (AEDT) in addition to the normal 9pm and midnight fireworks.
He said on Friday at White Bay, where seven tonnes of fireworks were being loaded onto barges, that organisers wanted to "fill that gap between 9pm and midnight".
"We (also) wanted something to keep the interest and build that anticipation," Mr Coffey said.
Tuesday night's fireworks will include 11,000 aerial shells and 25,000 shooting comets that will explode from seven barges on Sydney harbour.
For the first time in a decade, 1000 fireworks will also be shot from the top of the Opera House, as well as from the harbour bridge and jet skis stationed in the harbour.
AAP reports about 1.5 million people are expected at the harbour and another 1.1 billion worldwide will watch a telecast of the festivities.
The eight-hour show will cost the City of Sydney Council $A6.8 million and is expected to earn about $A156 million.
