Disgraced social media entrepreneur Belle Gibson has put forward a convoluted story that involves mysterious doctors, two birth certificates, a German cancer-detection machine and oral chemotherapy in her first televised interview after it was revealed that she had lied about having brain cancer.

Ms Gibson, who launched her top-rating food app and cookbook, The Whole Pantry, claims she was curing multiple terminal cancers with healthy eating, has since been found to have been lying about her illnesses.

Fairfax Media first revealed that she had failed to hand over thousands of dollars that she had promised to at least five charities earlier this year.

However, in an interview with 60 Minutes that began with a promise of honesty and transparency, Ms Gibson claimed she was telling the truth about "my reality".
