The actress made headlines earlier this year when it emerged her pet dogs had been brought into Australia without going through the regulation channels.
Amber is accused of failing to declare Yorkshire terriers Pistol and Boo when she arrived at Brisbane International Airport via a private jet in April.
She was in the country to visit Johnny as he filmed the fifth instalment in the Pirates of the Caribbean franchise.
At the time, a judge ordered the dogs to be removed from Australia or destroyed. Johnny and Amber complied by sending the pups back to the US.
Now, officials have charged Amber with two counts of illegally importing the dogs into Oz and one count of producing a false document. According to BBC News, penalties range from a fine of £48,000 to ten years in prison.
Amber has been summoned to appear in court on 7 September. Johnny has not been charged and is not required to appear.
Johnny and Amber have yet to comment.
