Ms Wilson successfully argued that a series of magazine articles had wrongly portrayed her as a serial liar.
In June a jury unanimously sided with Ms Wilson, who had claimed the articles stifled her career in Hollywood. She has said she will give the money away.
Bauer Media has always denied the articles were defamatory. A lawyer said it would consider the judgement.
Ms Wilson sought $A7m during the trial but had offered to settle for A$200,000 before it went to court.
