The top 24 contestants will no doubt be keen to hear a sample of Damien's first studio album Where We Land, which this week debuted at No.1 on the ARIA charts, following the success of his well-received second single "22 Steps".
"It definitely feels like it's a whole new phase," Damien told The Sun-Herald. "I'm so proud of the album, I really truly am. I feel really good about it."
The Irish-born singer has worked with legendary producer Ross Fraser and ARIA Award winning artist Alex Lloyd on the new CD, co-writing 10 of the songs.
2007 has been a massive year for the singer, kicking off with his The Winner's Journey album sitting at No.1 in the charts; he also became an Australian citizen, got the news his first novel was to be published and began work on the new album.
Topping it off, Damien and his wife Eileen welcomed their second child, son Jagger, in June.
If that wasn't enough his novel, One More Time, will be released in October. The book was written four years ago when Damien was trekking through Nepal, and he mysteriously describes it as, "almost a thriller but not quite".
In November busy Damien begins a tour of the east coast of Australia that will take in Sydney, Canberra, Brisbane, Melbourne, Newcastle, Wollongong and Hobart.
