Perth songbird Samantha Jade may well have secured her place in The X Factor grand finale after giving a show-stopping performance last night.
The challenge for the remaining six contestants was to tackle an iconic Aussie hit and mentor Guy Sebastian's decision for Jade to take on Sneaky Sound System's beat-pumping hit UFO had the judges and audience screaming for more.
Wearing a fluoro patterned cat suit, Jade took control of the stage with a series of dance moves as she belted out the popular track.
"You just topped it this week," Mel B said, while Ronan Keating agreed the song was well-suited to Jade: "Very cool … you've given us what we want."
In the wake of criticism about her recent shaky performances, 14-year-old Shiane Hawke stepped it up last night with a vibrant rendition of Vanessa Amorosi's hit, Shine.
The judges all agreed Hawke looked much more confident on stage.
Mentor Natalie Bassingthwaighte was beaming with glee: "I thought you were fantastic, I always do."
But not all acts felt at ease on stage last night. For the Collective's Trent Bell, the pressure of the looming finale began to take its toll during rehearsals.
His nerves seeped through his performance and saw the group give a less-than-impressive version of Timomatic's chart-topping hit, Incredible, which even Keating admitted wasn't their best.
An emotional Nathaniel Willemse fought back tears on stage as he gave a heart-felt rendition of Daniel Merriweather's hit Red.
Sebastian admitted he "choked up" watching him sing.
After winding up in the bottom two last week and then copping widespread hatred from Fourtunate fans on Twitter, Bella Ferraro was out to prove she still has what it takes to win The X Factor.
Singing the Temper Trap's Sweet Disposition, the 18-year-old's angelic vocals captivated all four judges. "Don't worry about the haters," Keating told her. "You are a talent … that was a beautiful, beautiful performance."
Small-town country teen Jason Owen wrapped up the night with a bang, with his take on Hoodoo Gurus' iconic track, What's My Scene.
