Tony Briggs and Keith Thompson's script for The Sapphires has taken out top honours in Australian Writers Guild awards, The Awgies, which were handed out in Sydney on Friday night.
The film was recognised with the best film screenplay award.
Briggs adapted his stage play of the same name with Thompson, for the screenplay about an indigenous singing troupe who took their soul act on an entertainment tour of duty, entertaining coalition troops during the Vietnam War.
Director Wayne Blair's film is currently reaping record returns at the domestic box office, having taken in excess of $6 million in its first fortnight of release.
Thompson previously won the best film Awgie in 2007 for his script of Clubland.
