When the members of the band chose to go their own separate ways in 2007, Rosenberg opted to stick with the Passenger moniker and took to busking. In October 2009, Mike first took himself over to Australia where he supported Lior and Sydneysiders Elana Stone and Brian Campeau, and then played One Movement, a major music industry-focus festival in Perth. For the release of his album "Flight of the Crow," he was joined in the studio by various Australian independent musical talents including Lior, Kate Miller-Heidke, Boy & Bear and Katie Noonan.
By the time Rosenber felt it was time to return to the UK to launch the album there, he was selling out 500-seater venues across Australia. His next album, "All The Little Lights," was recorded again in Sydney, and Rosenberg was joined once again by a core Australian band that included Boy & Bear drummer Tim Hart, jazz bassist Cameron Undy, who also played on Flight Of The Crow, and keyboards player Stu Hunter, from Katie Noonan & The Captains .
During the summer and autumn of 2012, Passenger toured around the UK, opening for Jools Holland, Ed Sheeran and joining Australian acts the John Butler Trio and Josh Pyke, with to co-headlined a UK tour. He also opened for Ed Sheeran's 2012 US tour.
The debut album Wicked Man's Rest was released in 2007 on Chalkmark. Wide Eyes Blind Love was released in 2009, followed by Flight of the Crow (2010). Divers and Submarines was a "fan-only" release in 2010. All the Little Lights was released in 2012.
