Written and produced by OneRepublic frontman Ryan Tedder, the song was released by Sony Music Australia on 12 April 2010 as the lead single from Walker's second album, From the Inside Out.

"Unbroken" was written and produced by OneRepublic leader Ryan Tedder, who was behind singles such as Beyoncé Knowles' "Halo" (2009) and Leona Lewis' "Bleeding Love" (2007).

[7][8] The Compact Disc single for "Unbroken" was released in Australia on 24 April 2010; it features an Israel remix and the a cappella version of the song.

Scott Kara of The New Zealand Herald called it "chest-beating and uplifting",[10] while Allmusic's Jon O'Brien saw the song as very similar to Tedder's previous writings.

[18] Walker said to MTV's Clippin' that shooting the video in public made him feel embarrassed and he found it difficult not to laugh during its filming.

[20] The video opens with the camera rotating around Walker at an intersection as he slowly raises his head,[20] before he is shown walking down a shop-lined street.

Examples of broken people are shown, such as a girl being pushed around and teased before she plugs headphones into her ears, a man watching over a hospital patient, and individuals waiting for others to show up.

At the end of the video the now "unbroken" characters shot in Martin Place are shown to be content, and Walker makes his way down a darkened alley.
