Script-writer and director.
Barrett was trained at the Australian Film, Television and Radio School, at which she wrote and directed the short film Cherith (1987): the film (distributed on VHS by the Australian Film Institute) won her two awards, including an AFI Award for Best Short Fiction Film. Around the same time, Barrett was involved with the Australian Children's Television Foundation program Kaboodle, which aimed to give industry assistance to up-and-coming television writers and directors: Barrett contributed the ten-minute fantasy film 'The Kobold and Potato' (directed by Karin Altmann) to episode nine of series 1.
For the first few years of the 1990s, Barrett worked primarily as a director, directing episodes of such television programs as Boys from the Bush (1991), A Country Practice (1992-1993), Heartbreak High (1994), and Police Rescue (1995).
In 1996, she wrote and directed Love Serenade, which won her the Golden Camera at the Cannes Film Festival, as well as attracting two AFI Award nominations (for Best Achievement in Costume Design and Best Achievement in Production Design): at the Valladolid International Film Festival, Barrett won Best New Director for the film, and was nominated for the Golden Spike. Barrett followed this with the feature films Walk the Talk (2000) and South Solitary (2010). She also wrote the scripts for the short film Steamboat (2009), directed by C.J. Johnson, and for one of the four parts of anthology series Before the Rain (2010), produced by the Australian Film, Television and Radio School (the other three parts were written by Alice Bell, Christopher Lee, and Judy Morris, and the program was directed by Craig Boreham, Nick Clifford, Stephen de Villiers, and C.J. Johnson).
At the same time, Barrett continued to work in television, directing episodes of Love My Way (2006-2007) (for which she won a 2006 AFI Award for Best Direction in Television, for her work on episode 11), Packed to the Rafters (2011), Wild Boys (2011), Offspring (2010-2012), and, House Husbands (2012).
