Working for free, having your voice dubbed into Swahili and handing over recording rights of your singing to any technology, both current or invented by an alien race of funky superbeings, are just some of the clauses contestants of the Seven Network's X Factor must agree to to appear on the television talent show.

A 66-clause contract typed in small print, and obtained by Business Day, reveals the extent to which X Factor contestants and pop-star wannabes must sign over their lives to have the chance to appear on the global hit television talent search program.

Watertight: To perform in front of the X Factor hosts, contestants have to agree to a number of conditions.

Currently on air in its fifth season, X Factor's judges this year are Kylie Minogue's sister Dannii, bodyrocker and LMFAO frontman Redfoo, Irish boy band graduate Ronan Keating and former Neighbours star Natalie Bassingthwaighte.

The extensive and detailed contract seeks to govern the behaviour of contestants as they compete and progress through the talent search as well as after the show is completed, including using vision of their performance 'in perpetuity'.
