Deborah Mailman had a supporting role in season 1 of the limited TV series Mystery Road starring Aaron Pedersen and Judy Davis, a spin-off from Ivan Sen's films Mystery Road (2013) and its sequel Goldstone (2016).

Mystery Road is a crime drama set in the outback about 2 young farm hands who mysteriously go missing. When one of the boys shows up, he becomes a suspect in the other’s disappearance.

Mailman plays Kerry, the mother of the accused boy, Marley (Aaron L McGrath). In this short excerpt from episode 4 we see her confronted by Detective Jay Swan (Pedersen).

Although the scene is only brief, it’s a great example of how much tension and emotion Mailman brings, even to a supporting character.

In Mystery Road, Mailman also worked with directors Rachel Perkins, Warwick Thornton and Wayne Blair, all of whom she has collaborated with on prior productions. She appeared opposite Aaron Pedersen in Jack Irish, also released in 2018.
