Late Adelaide actor Paul Blackwell also posthumously won the Helpmann Award as best supporting actor for his role in State Theatre Company of SA’s play Faith Healer on Sunday.
SA won a total of eight awards from 25 nominations.
Another seven awards, including Best New Australian Work and Best Play, were won by the Sri Lankan epic Counting and Cracking which was produced by Sydney’s Belvoir theatre company and Co-Curious, but was also co-commissioned by and performed at this year’s Adelaide Festival.
They were among a total of 13 awards won by Belvoir, which also created the production of Faith Healer.
