The Australian actress, who won the AACTA Award for 'Best Supporting Actress' for her role in the movie on Tuesday night, said that she feels smug now because Wilkins gave the film "zero out of five stars" in a review when it first came out.
When asked what she would say if she saw Wilkins now, Harris told The Advertiser: "I'd say, 'You're a w**ker, mate'. I'd say, 'Sucked in'. We got the last laugh, didn't we?"
Snowtown's director Justin Kurzel, who won the 'Best Direction' AACTA, diplomatically added that Wilkins was "entitled to his opinion" about the film based on mass murders in South Australia.
Snowtown also won awards for 'Best Sound', 'Best Actor' for Daniel Henshall, 'Best Editing' and 'Best Adapted Screenplay' for Shaun Grant.
Other winners included Red Dog for 'Best Film', The Eye of the Storm's Judy Davis for 'Best Actress' and Hugo Weaving from Oranges and Sunshine for 'Best Supporting Actor'.
