Justin Dallas Kurzel was born around 1974 in Gawler, South Australia to a Polish father and a Maltese mother. His younger brother, Jed Kurzel, is a blues rock musician who has scored all of Justin's feature films.

He first trained at the National Institute of Dramatic Art, graduating with a Bachelor of Dramatic Art (Design) in 1995, and then later studied at the Victorian College of the Arts School of Film and Television.

In 1999 Kurzel was awarded a Mike Walsh Fellowship. His Victorian College of the Arts graduating short film Blue Tongue (2004) screened in over 13 international films festivals and won Best Short at the Melbourne International Film Festival.

Kurzel's feature film debut was Snowtown (2011), for which he won the AACTA Award for Best Direction. Though controversial for its violence, the film was generally praised and holds an 84% on Rotten Tomatoes with the critic consensus: "It's a bleak and brutal endurance test, but for viewers with the strength and patience to make it to the end, Snowtown will prove an uncommonly powerful viewing experience." The film marked Kurzel's first collaboration with writer Shaun Grant.

His 2015 film adaptation of William Shakespeare's Macbeth was selected to compete for the Palme d'Or at the 2015 Cannes Film Festival.

In 2016, Kurzel directed Assassin's Creed, based on the video game franchise of the same name.

Kurzel directed True History of the Kelly Gang in 2018, adapted from Peter Carey's 2001 Man Booker Prize-winning novel of the same name, written from the viewpoint of legendary Australian bushranger and outlaw Ned Kelly. The film premiered at the 2019 Toronto International Film Festival and was released in Australian cinemas in 2020.
