Cancer con artist Belle Gibson will be hauled before court to explain her failure to pay a $410,000 penalty for duping Australians.

The fake wellness guru has been summoned to appear in the Federal Court on May 14 for examination on her financial affairs, following her non-compliance.

Belle Gibson has failed to pay a penalty slapped on her in 2017.

She has already been warned she faces jail for failing to pay the penalty, imposed on her in 2017 by Federal Court Justice Debra Mortimer for five breaches of consumer laws.

Gibson claimed she had brain cancer and healed herself with natural remedies, including diet and alternative therapies.
