The model and actress flew into Sydney on Monday morning (May 21) for a meeting with director George Miller, according to the Australian Daily Telegraph.
Both Huntington-Whiteley and Miller were spotted yesterday at the Juanita Nielsen Community Centre in the harbourside suburb of Woolloomooloo yesterday (May 22). The private studios at the centre are often used for casting calls.
Huntington-Whiteley, who has previously modelled for brands including Burberry, Agent Provocateur and Victoria's Secret, made her acting debut last year opposite Shia LaBeouf in Transformers: Dark of the Moon.
Batman: The Dark Knight Rises star Tom Hardy has been cast in the lead role in Mad Max: Fury Road, and recently said that he is unsure when filming will begin as the dates keep moving around.
He also jokingly told reporters at the Cannes Film Festival that the movie would be "a live, free-running musical" in which the cast would "go around shopping centres in a little wagon and sing songs".
