It’s half a century since the infamous drowning of Dr George Ian Ogilvie Duncan; a moment in time that triggered an alleged police cover-up, a city-wide scandal, national outrage, a Scotland Yard investigation… and a glaring absence of convictions.

Watershed, a ravishing new operatic work and the hit of the 2022 Adelaide Festival, is a collaboration between some of Australia’s most acclaimed creative talents.

Helpmann Award-winning playwright Alana Valentine and author Christos Tsiolkas (The Slap) have created a searing, no-punches-pulled libretto. Brisbane composer Joe Twist’s score is luscious and ultimately transcendent. And Australian theatre and opera legend Neil Armfield’s production is as deeply felt as it is thrillingly physical.
