Original members of The Wiggles said farewell on Saturday night at Sydney's Carols in the Domain.
The popular annual event began with a rendition of O Come All Ye Faithful at 8.30pm (AEDT) by The Ten Tenor's.
AAP reports the cheers really kicked off when Australia's most loved children's music group said their final goodbye to the event.
"Three of the members are hanging up their skivvies so tonight is their very last television performance before handing over to new band members," Carols co-host Natalie Barr said.
"So this is it Australia, the end of an era," Matt White said.
The crowd jumped to their feet, shooting out arms and legs in unison with the original Red, Yellow, Red, Purple and Blue wiggles as they sang and danced to Fruit salad, Hot Potato and Jingle Bells.
"The Wiggles have been performing at Carols in the Domain for 20 years ... and we have always had such a wonderful time," Red Wiggle Murray Cook said, adding that next year will see the three new Wiggles perform.
Also in the evening: AAP reports Georgie Parker and Jay Laga'aia teamed up for Here Comes Santa Claus and Rudolph The Red Nosed Reindeer, eliciting a big cheer from the crowd.
Troy Cassar-Daley sang Have Yourself a Merry Christmas and Jingle Bell Rock later.
