Peaches Geldof planned to move Downunder to replace troubled Kiwi TV presenter Charlotte Dawson on Australia's Next Top Model.
Former model Geldof, 25, who died suddenly on April 7 at her home in Kent, England, was in talks to appear on the hit show after Dawson's suicide in February.
Troubled Dawson, 47, was found dead in her luxury Sydney home by a real estate agent when he arrived to inspect the property ahead of its auction.
Dawson, who had long battled depression, had been axed by Australia's Next Top Model in November and was unhappy about not having any work lined up this year.
In a tragic twist, mum-of-two Geldof was set to take her place as a judge and model mentor and was one of several candidates shortlisted for the role.
