[1] In 1970, Hibberd played a pivotal role in establishing the Australian Performing Group (APG), where he remained an active member for a decade, including a two-year tenure as chairman.
His next play, a long monodrama, A Stretch of the Imagination, is regarded by most connoisseurs as his finest work, embodying a radical advance in the character of Australian theatre, embracing and remoulding as it does many of the strong strands in theatrical modernism.
Hibberd completed some stage adaptations of short stories: Nikolai Gogol's "The Overcoat" (with music), Guy de Maupassant's "Odyssey of a Girl [fr]", and Leo Tolstoy's The Death of Ivan Ilyich.
The first entails a preparation for a wedding (a fantasy performance), the second explores the fine public face of grief and its ugly private underbelly.
Apart from Stretch, there is a gargantuan male on monodrama, From Apes to Apps, subtitled A History of the Western World in Ninety Minutes.
Peggy Sue, a companion to White with Wire Wheels, dramatises the mistreatment and exploitation of three romantic young women during a severe economic depression when they are compelled to work as prostitutes.
Repossession concentrates on the conflicts between two poor young women who live in a shack out in the bush and two domineering corporate captains who, stranded, turn up for the night.
With the help of a suave Sydney detective, she weaves her way through Melbourne's unsavoury and ethnically diverse underground, finally finding and nailing the Big Drug Baron, a toad-featured Australian Vietnam Vet, who originally went AWOL into the Golden Triangle.
He enlists the aid of black Americans and Africans, who infiltrate Australia, bomb Parliament House killing all its members, and seducing paddocks of white women.
Uncle Sam Uncle Sam, who has been wrongfully incarcerated in the Hollywood Hospital for the Psychiatrically Challenged, escapes with the help of Charlie Chan, and begins a presidential campaign, assisted by an unlikely and incredible electoral team, including, among others, Black Hawk, Davy Crockett, Paul Bunyan, Mark Twain, Superman, Eleanor Roosevelt, Zapata, George Washington, Janis Joplin, Curt Cobain, Rabbi Harpo Marx, and Mr Ed.
To cut a long narrative short, Uncle Sam's truly liberal and leftish platform, along with his witty savaging of his two opponents and avaricious corporations in a television debate, leads to a refreshing and volcanic victory.
