The singer will include new cut ''Cos You're Beautiful' on upcoming retrospective collection This Is It: The Very Best Of next month.
The track was co-written by Ruth Lorenzo, who Dannii mentored during the fifth series of The X Factor in the UK back in 2008.
The greatest hits set will also feature Dannii's duet with her sister Kylie Minogue for a cover of ABBA's 'The Winner Takes It All', which was originally on the soundtrack of BBC series Beautiful People.
However, the 24-track-long collection - which also feature hits 'Put The Needle On It' and 'I Begin To Wonder' - is currently only scheduled for an Australian release on August 23.
