JOHNNY Depp has been likened to the Godfather in his video apology over his dogs with deputy PM Barnaby Joyce urging the Hollywood star to "do it again'' with a 'little gusto'".

"What I can say is although I don't think he'll get an academy award for his performance, the fact that he did it … he looked like he was auditioning for the Godfather,'' Mr Joyce told the ABC.

"At the end of it we've got a message that is going all around the world right now, it's going off like a frog in a sock telling people that if you come into this nation and you don't obey our laws, you're in trouble.

"That's what this is about, it's making sure we keep this nation, protect our flora, our fauna and protect our biosecurity laws."

Mr Joyce told Seven's Sunrise show that he could have done a better job directing the video, saying Depp should "rise to the camera".

Minister Joyce's office said Depp's wife Amber Heard had "offered to publicly state her contrition with the support of her husband".

"The Department of Agriculture and Water Resources provided input concerning the offence and biosecurity messaging in consultation with the Commonwealth Director of Public Prosecutions (CDPP),'' a spokesperson said.

"The video was produced by the defendant and there was no cost to the department.

"The department was provided a copy of the video late (Sunday) night.

Ms Heard was handed a one-month good behaviour bond with no conviction recorded after smuggling her two Yorkshire terriers into Australia last year while visiting Depp.
