Cancer con artist Belle Gibson has been warned she faces jail over her failure to pay a $410,000 court fine for duping Australians.

The fake wellness guru was penalised in the Federal Court in September last year for five breaches of Australian Consumer Law, after falsely claiming she had brain cancer and healed herself with natural remedies.

She also lied to supporters about donating money from her Whole Pantry app and book sales to various charities, including a boy with inoperable brain cancer.

Federal Court Justice Debra Mortimer issued a warning to Gibson on Tuesday that failure to pay the penalty will make her liable for jail, property seizures or other punishment.

“You will be liable to imprisonment, sequestration of property or other punishment,” the penal notice says.

Anyone else who is aware of the order and helps or allows Ms Gibson to breach it may be punished in a similar way, the notice states.

The director of Consumer Affairs Victoria, who brought the case, and Ms Gibson and her company Inkerman Road Nominees, have until December 11 to make any submissions.
