There have been very few silent nights following Greenfield Park singer Olina Loau's break-out year in 2019.
And the 16-year-old is set to jingle all the way through to the end of the year.
The Bossley Park High School student has been announced alongside Mark Vincent, Lucy Durack and Todd McKenney as the first performers for Carols in the Domain on Saturday, December 21.
The teenager burst onto the national scene this year with a top four finish on Australia's Got Talent where she produced two golden buzzer performances in a journey she described as "crazy, hectic, fun and hard."
"I was practising with my aunty Helen and she said 'what's that big event you wanted to do?' and I said 'Carols in the Domain'. She said 'you got something for that'. I started jumping and screaming when I found out I will be performing. It is very exciting. Christmas is my favourite holiday," she said.
"This year has definitely been my strongest in terms of performing and Carols in the Domain is the perfect way to wrap up the year."
Olina, who practises her singing technique daily, will perform one Christmas carol (to be revealed on the night) at the 37th annual event.
She is also preparing for her sixth appearance at this year's Schools Spectacular on November 22 and 23.
The year 10 student will be singing musical icon Beyonce's Listen - the same song she performed in the AGT semi-final while standing in water - which she described as her "favourite" on stage moment.
Olina, whose brother Ezra is also a featured performer at this year's Schools Spectacular, will back up to belt out a rendition of Rewrite The Stars from hit movie The Greatest Showman as part of a duet.
Next year promises to be another big one with a few "exciting" things in the pipeline. Her ultimate goal is to replicate Beyonce and perform at the Super Bowl.
