The tour began in April 2010, and was set to take place until 2012, though following frontman Deryck Whibley sustaining a serious back injury, the tour was cut short in August 2011, and all following dates until the end of 2011 were cancelled, to let Whibley undergo a treatment and recover.

On this leg, the band played a total of 13 dates in mostly small venues, almost all of them sold out, and debuted the single "Screaming Bloody Murder" live for the first time.

After playing two dates in Brisbane and Sydney, it was announced on February 28, that Deryck was hospitalized with severe pneumonia and the band will be cancelling the rest of their Australian tour.
