The government body conducting an independent audit into the use of public funds by Barnaby Joyce and Vikki Campion, says the invetigation is not yet over.
Both Mr Joyce and Ms Campion have flatly denied misusing any public funds.
During the couple's controversial TV interview, Mr Joyce said he’d gone through comprehensive questioning by the Independent Parliamentary Expenses Authority (IPEA).
“They have investigated this to death,” Mr Joyce said.
“I’ve had like 160 inquiries and at this point not one, not one, has come up saying ‘Oh, this is a problem’.”
Ms Campion, who is also having her expenses investigated, said “they have found that they actually owe me money”.
However the IPEA said it was still investigating the pair.
“At this time the audit remains ongoing and we are unable to provide a timeframe for completion,” an IPEA spokesperson said.
“To comment on any particular matter that may or may not be under consideration may compromise the conduct and outcome of any audit and the privacy rights of individuals.”
The organisation also stated it took it’s Freedom of Information (FOI) obligations seriously, despite recently coming under fire for knocking back various FOI requests regarding the pair's travel expenses.
In March, The Leader reported its FOI request for Ms Campion’s travel expenses had been denied by the IPEA on due to the “expectation and risk” of the information being “misinterpreted and misrepresented”.
IPEA also feared the releasing the information would undermine its investigation.
In May, the organisation denied travel records denied, claiming the information could “endanger life”.
