The 2015 grand winner of “X Factor” Australia will be revealed Tuesday night.

The top three vying for Australia’s “X Factor” title – Cyrus, Louise Adams, and Jess and Matt – take the center stage Monday night and performed three songs each.

The first was their audition number, followed by a track chosen by their mentor, and finally a potential debut single, the Daily Telegraph wrote.

Jess and Matt did not disappoint the judges and the audience with their renditions of Vance Joy’s “Georgia.” The lovebirds also performed their mentor Guy Sebastian’s chosen track – Sam Smith’s “Lay Me Down” – and their would-be winner single “Nothing Matters.”

Sebastian said Jess and Matt are the first duo to ever make it this far in the Australia’s version of “X Factor.”

“There’s no one like you in this country. You offer something so special,” said Guy.

Fellow mentor/judge Dannii Minogue dubbed the duo as the “ones to beat” and pointed out they had already amassed half a million sales on iTunes, Daily Mail wrote.

Chris Isaak also praised Jess and Matt and said: “You guys have come a long way. You have really grown through this process.”

Louise, meanwhile, proved why she deserves to be on the Top 3.

She revisited her audition song “Feeling Good,” and blew away the audience with her rendition of Adele’s “Someone Like You” which her mentor James Blunt picked for her. She also performed her winner’s debut song “History,” Yahoo News wrote.

Isaak was impressed with Louise performances and said: “You are the queen of the big notes. That was pretty darn impressive.”

Blunt told the 31-year-old new mom that she has the most unique voice in the competition. The British singer added: “You blew me away, you blew these guys away!” and then urged viewers to vote for his contestant.

Cyrus, on the other hand, performed his audition track The Weekend’s “Earned It,” then sang his rendition of Labrinth’s “Jealous,” and pleased the crowd with his potential debut single “Stone.”

Cyrus’ “Jealous” performance brought his mentor Isaak to tears. Chris said: “I might need that handkerchief back,” as he struggled to contain his emotions.

“You definitely earned your position here in the Grand Final. You can sing anything!” Sebastian commented.

Meanwhile, sisters Kylie and Dannii Minogue are set to perform tonight on “X Factor” stage. Fans will also see performances from Jason Derulo, Rudimental, and judge James Blunt. All of the Top 12 contenders will also return with a special number in tonight’s show.

“X Factor” Australia grand final airs tonight at 7:30 pm on Channel Seven.
