The Australian Idol Grand Finale performance show saw the Top 3 finalists – Gisella Colletti, Iilysh Retallick, and Marshall Hamburger – deliver impressive solo numbers and duets with music stars, setting the stage for Monday’s live winner announcement.
Here’s the Lowdown: On Seven and 7plus, 17-year-old Gisella Colletti (WA), 17-year-old Iilysh Retallick (NSW), and 19-year-old Marshall Hamburger (QLD) performed individually. Marshall tackled John Farnham’s “Playing to Win,” Gisella sang Whitney Houston’s “How Will I Know,” and Iilysh performed Divinyls’ “Boys in Town.” They also paired up for duets: Iilysh with Wolfmother (“Joker and the Thief”), Gisella with Tina Arena (“Heaven Help My Heart”), and Marshall with Leo Sayer (“You Make Me Feel Like Dancing”).
What This Means Now: The competition is down to the wire, with Australia’s vote set to determine the winner during the live show on Monday at 7:30 pm. Each finalist made their final case through these performances, hoping to secure the title, $100,000 prize money, and a recording package with Hive Sound Studios.
The Bigger Picture: The finale night also featured a performance by judge Marcia Hines with former winner Casey Donovan, who reminisced with host Ricki-Lee about their shared Idol season 21 years prior. Monday’s live verdict show will see the Top 12 return and a performance from Idol original Guy Sebastian, concluding the 2025 search for the next Australian Idol.
