The group teamed up with their previous producer Eliot Kennedy to record their ninth studio album, "A Symphony of Hits", with the Prague Philharmonic Orchestra. It was released on 10 November 2008, which peaked at No. 10. Adam Greenberg of AllMusic explained that "he vocals are consistently strong, though they are undeniably of the boy band variety. There's melodramatic emotion pumped into everything here. While it works well for some of the ballads (the Bangles' 'Eternal Flame' in particular comes off well), it can seem a little much for the bouncier tracks." They followed in mid-December with three performances at the Sydney Opera House fronting the Sydney Symphony Orchestra, conducted by Guy Noble. They also performed with the Melbourne Symphony Orchestra in Melbourne (February 2009), and the West Australian Symphony Orchestra in Perth (February–March).
