П. O. was inspired to start writing poetry in 1973 when he heard Johnny Cash reciting (religious) poetry while tuning his guitar. П. O. thought he could do as well or better. His work ranges from standup-type rants to 'conceptual' page poetry and concrete poetry, with a heavy emphasis on wordplay and capturing the vitality of everyday speech. Thematically, he commonly portrays the issues of non-Anglo-Celtic working class life.[2]
His first published book, Fitzroy Brothel, was released in 1974. From 1978 to 1983, he was involved in producing the radical poetry magazine 925. After the publication of several more collections, his 740-page epic poem 24hrs was published in 1996 by Collective Effort Press.
He is a fixture of Melbourne's performance poetry scene and has edited an anthology of performance poetry (Off the Record) for Penguin. He has been editor of the literary journal Unusual Work.
