Barnaby Joyce has taken aim at his nemesis Johnny Depp once again, this time claiming the Hollywood actor may have 'perjured himself.'

Court documents have revealed former business managers said Depp was 'fully aware that he was illegally bringing his dogs into Australia' and allegedly lied to authorities when he claimed to have accidentally smuggled the pups into the country.

'If the allegations that have been made against him are correct, and I’m not saying if they are or aren’t, then that would be perjury,” the deputy prime minster told the Herald Sun.

The star was filming the latest installment to the Pirates of the Caribbean series in May 2015 when he was publicly confronted by Australian authorities about his dogs, Pistol and Boo.

According to legal documents obtained by People filed by his former business managers, The Management Group (TMG), Depp 'falsely claimed' to authorities and the press that the incident was a misunderstanding.

He told the public that he 'believed his staff had obtained the necessary paperwork'.

The legal documents are a part of a court battle between Depp and TMG, the group he claims defrauded him out of millions of his earning.

But TMG says that Depp's wild spending left him unable to pay debts.

According to People, when Depp was confronted by Australian authorities, TMG claimed that he 'pressured one of his long-term employees to 'take the fall.''

Depp's ex-wife Amber Heard avoided jail time when she pleaded guilty to falsifying border protection documents when when she imported the teacup Yorkshire terriers into Australia.

Heard was handed a one-month good behavior bond and fined $1,000.

The incident sparked global headlines when Joyce said the dogs had better 'bugger off' back to the US or he'd arrange to have them put down.

It was alleged the pooches were not declared to customs officials on arrival.

The presence of the A-list canines was only discovered when their visit to a Gold Coast dog grooming salon was made public.

The dogs were quickly whisked out of the country before a 72-hour deadline lapsed when the canines would have to be seized.

Under strict Australian laws designed to keep disease at bay, dogs entering from the United States must be declared and have to spend 10 days in quarantine.

Penalties for contravening the Quarantine Act range from fines to a maximum of 10 years in prison for the worst cases.

Depp was never charged over the incident.
