Amber Heard is being investigated for perjury in an FBI-backed probe into claims she lied to Australian officials after smuggling her dogs into the country in 2015.
Aussie authorities are revisiting the smuggling spat as a perjury investigation after fresh details dredged up at last year's UK libel trial between Heard's ex, Johnny Depp, and The Sun newspaper, called her explanation into question.
Depp's former estate manager Kevin Murphy raised eyebrows Down Under when he told the London court that Heard had ordered him to lie on oath after she flew the pets into Queensland in a private jet without declaring them.
The Department of Agriculture, Water and the Environment responded by quietly reopening a criminal probe and enlisting the help of the FBI to track down witnesses in the US.
One of those, Murphy, has now been interviewed at length by Australian investigators and has provided a lengthy witness statement and a trove of emails allegedly implicating Heard.
Sources close to the investigation believe she could be weeks away from being hit with charges of perjury or subornation of perjury, which involves inducing someone to provide false testimony.
Perjury carries a maximum jail term of 14 years while the latter offence can result in a seven-year stretch under the Queensland penal code.
It's unlikely the Australian government would try to have Heard extradited, but she could nonetheless face arrest if she tried to enter the country again.
'She could just ignore the whole thing and never go back but a huge number of movies are shot in Australia, including Aquaman, the movie for which she's most well-known,' dished an insider.
The department is seeking to obtain witness statements and once obtained, the Commonwealth Director of Public Prosecutions will consider whether the evidence is sufficient to warrant pursuance of the matter. As the matter is ongoing, the department cannot make any further comment.'
