A never-before-seen sparkling musical note firework will light up the Sydney skyline this New Year's Eve in honour of singer Kylie Minogue.
As creative ambassador for the event in 2012, the pop princess developed the event's theme "embrace" and chose its colour scheme and soundtrack.
She arrived in Sydney early on Friday to put the finishing touches on the displays.
Event producer Aneurin Coffey said Minogue had been a hands-on creative ambassador.
"She's been a lot more involved than we expected. When you actually get someone like Kylie on board you never know quite what you're going to get, but she was absolutely ecstatic to be involved," he told reporters gathered on the harbour on Friday.
Punters should look out for a "special moment" as the singer helped launch Monday's spectacle, he said.
Fireworks director Fortunato Foti said he and his family's company built the semiquaver from scratch to celebrate Minogue's 25 years in music.
"There was a lot of work done to get it there, and hopefully it will work out the way it's supposed to on the night," he said.
"What we aim to do (each year) is to make it the best one - for people to go away and say `that was the best display I've ever seen'."
This year brings together three generations of the Foti Fireworks family, with high school graduate Elena Foti, 18, joining her father Fortunati and grandfather Sam in the preparations.
She told reporters on Friday she wasn't getting any perks as the boss's daughter.
"I'm the rookie," she laughed.
The fireworks displays are made of about seven tonnes of pyrotechnics, which were on Friday unloaded onto barges at White Bay, in Sydney's inner-west.
Some 11,000 shells and 25,000 shooting comets will explode off seven barges spread across six kilometres of Sydney Harbour.
The Sydney Harbour Bridge alone has 120 firing points across its one-kilometre span.
