The Voice - Season 4 (2015)

The fourth day provides one of the most moving performances in The Voice's history when a wheelchair bound artist defies the odds and delivers a moment that moves everybody to tears.

The blind auditions pass the halfway mark, and for both the artists and coaches, the pressure mounts. Two teenage best friends compete against each other on the stage, but can they both get the chairs to turn?

The tension between Jessie and Delta heats up. The coaches are stunned by a mesmerising performance from a young busker.

The mounting tension between Delta and Jessie reaches its climax when Delta takes a time out after a heated exchange during a contestant's feedback. Several contestants fail to make it through. Jessie J gives some encouragement to an audience member during a break, and gives another fan an unforgettable experience.

The second last day of the blind auditions begins with the coaches feeling the heat. The Maddens, Jessie and Ricky go head to head as they try to secure their teams' final three places, but Delta is in front with two spots left on her team.

As the final day of the blind auditions begins, Jessie J is searching for two more artists, while the Madden brothers, Delta and Ricky each have one place yet to be filled.

The first team members go head to head in the battle ring. The coaches then have to choose who wins, who loses and who they will steal from another team.

The second night of battles is a heated one as each coach puts four more artists into the battle ring, before deciding who wins, who loses and who they will steal from another team.

The final four artists from each team go head to head in the battle ring. Only Delta and the Madden brothers have one more chance to steal a losing artist from another team.

The coaches give two of their final 8 artists a Fast Pass to the live finals. The other 6 artists are divided into two battle trios, where each artist sings their own song, with a common theme linking the three songs of each trio, from which the coaches choose one artist to go through to the live finals.

The sixteen remaining artists take to the stage for their first live performances, then each coach decides which of their artists they will send through to the next round, leaving the other artists in their team to face a public vote.

The artist from each team that receives the fewest votes is eliminated from the competition. The twelve remaining artists take to the stage for their second live performances, then their coach chooses one artist to send to the next round, leaving their other two artists to face a public vote.

The three remaining artists in each team perform with their coach as a group, then the artist from each team that receives the fewest votes is eliminated from the competition. The eight remaining artists take to the stage for their next live performances, then their coach chooses one artist to send to the semi final, leaving the other four artists to face a public vote.

The four artists facing the public vote take to the stage again to sing for their survival before the results of the public vote are revealed, and the two artists that receive the fewest votes are eliminated from the competition. The remaining six artists take to the stage for their next live performances, then face an instant save that will see four of them go through to the grand final.

The final four artists take to the stage for a solo performance and a duet with their coach, then the voting lines are closed and the two artists that receive the fewest votes are eliminated from the competition. The two remaining artists perform an original song before the artist with the most votes is revealed and crowned The Voice of Australia for 2015.
