‘X Factor Australia' 2016 latest news: Four acts to be eliminated; Adam Lambert’s risky song choices pay off as his team dominates the night [VIDEOS]

“X Factor Australia" is determined to deliver the most exciting year yet, and the surprises started on its first live episode this season.

On Sunday, this year’s contenders – and fans – were shocked when they were informed that four acts will be sent home in the next live episode. After winning judges Guy Sebastian, Adam Lambert, Iggy Azalea and Mel B, the top 12 – including Mel’s underdogs – auditioned for the nation. They only have one chance to make an impression and those who fail to deliver will end their “X Factor Australia" 2016 journey on Monday.

In one teaser, Adam says he’s excited to work more closely with his picks for the Under 22s category: Natalie Ong, Amalia Foy and Isaiah Firebrace. It seems that the “American Idol” runner-up really knows his business – every single act from his team set the “X Factor” Australia stage on fire. Fan favourite Natalie blew the judges away with her rendition of “When Love Takes Over” by David Guetta and Kelly Rowland. The Singapore-born young student earned the highest compliment – a standing ovation from all of the judges.

Adam’s two other acts, Amalia and Isaiah, also made their mentor proud. Amalia nailed Sarah McLachlan’s challenging ballad, “Angel,” while playing the piano. She brought Adam, Guy and Iggy up to their feet, but Mel B said she was a bit bored by the performance. The three judges – minus Mel B again – also gave a standing ovation to Isaiah, who sang “Lay It All On Me” by Ed Sheeran and Rudimental. Without a doubt, Adam was one happy camper with his team’s performance. It would be interesting now who among the three would be sent home by the viewers.

For the other categories, the acts on the chopping block seem to be an obvious choice. Timmy Knowles from Guy’s Over 22s category, who sang Selena Gomez’s “Hands To Myself” gave a mediocre performance. Iggy’s boyband, Time and Place, also failed to impress with their rendition of “Ride” by Twenty One Pilots. Maddison Milewski, who’s part of Mel B’s Underdogs category, didn’t make an impact on the judges with their performance of “Addicted To You” by Avicii.

Based on their performances on Sunday night, the following acts are likely to stay in the competition:

Iggy’s Groups
-- Aya (formerly known as Montage), “Secret Love Song” by Little Mix
-- Brentwood, “Say It” by Flume featuring Tove Lo

Guy’s Over 22s
-- Davey Woder, “With A Little Help From My Friends” by Joe Cocker
-- Chynna Taylor, “Open Arms” by Journey

Mel B’s Underdogs
-- Beatz, “Sax” by “X Factor” UK alumni Fleur East
-- Vlado Saric , “Closer” by the Chainsmokers
