Australia's sweetheart welcomes Australian and international stars, performing all time Christmas favourite Silent Night with Mitch Tambo on didgeridoo, and joining star of Hamilton Jason Arrow for a rendition of One Little Christmas Tree arranged especially by the New York Hamilton team.

Goodrem will duet with Take That lead singer Gary Barlow and British R&B crooner Craig David.

"I'm so grateful to all the incredible artists and dear friends of mine from around the world who have joined me this year to bring to life our second Christmas special," Goodrem says.

Among others to perform are Natalie Imbruglia, Cody Simpson, Sheppard, guitarist Harts, and Paul Kelly.

No Christmas show is complete without a choir and the soulful sounds of the Melbourne Gospel Choir fit the bill.

Goodrem promises "a truly magical night full of festive cheer and holiday spirit, celebrating Christmas the Australian way".

In the spirit of giving, and courtesy of Tourism Australia and Santa's helpers Hamish and Zoe Blake, there will be some heartwarming reunions for deserving Aussies separated from loved ones due to border restrictions.

Plus, in an unforgettable finale, incredible tenor Andrea Bocelli joins Goodrem in a haunting version of Amazing Grace.

Delivering Christmas favourites and heartwarming surprises, this special will set the tone for a happy festive season.

"It really is a show I'm proud of for the whole family to enjoy."
