Paul Hetherington was born in Adelaide in 1958, one of twin sons of Robert and Penelope Hetherington (née Loveday). His family moved from Adelaide to Perth in 1966.

Hetherington was educated at The University of Western Australia, completing a double major in English and History and sharing three student prizes in his honours year: the Gladys I Wade Prize, the James Bourke Memorial Prize and the Convocation Prize in Arts.

Before moving to Canberra in 1990, to take up a position at the National Library of Australia, Hetherington worked as a sessional tutor in the English Department at the University of Western Australia (1985-88) and in 1989 was employed at Fremantle Arts Centre as Publications and Events Coordinator.

Hetherington has been a member of a variety of Boards, including the Board of ABR, and was a judge for the 2006, 2007 and 2008 ABR poetry prizes and the 2007 CAL/ABR Calibre Essay Prize. He was a member of the steering committee that established the ACT Writers Centre (1994-95) and Chair of the inaugural ACT Writers Centre’s Committee of Management (1995-98).

As of 2017, Hetherington has published 11 volumes of poetry (and, more recently, prose poetry), including a verse novel, Blood and Old Belief, and five chapbooks. He has won or been shortlisted for numerous poetry awards in Australia and internationally. He founded the international Prose Poetry Group in 2013 as one of IPSI’s activities and has collaborated on creative and scholarly projects with a number of writers and academics including Jen Webb, Anita Fitton, Antonia Pont, Rachel Robertson, David McCooey, Cassandra Atherton, and Phil Day.
Paul Kane (q.v.) has written: 'One of the first things one notices about Hetherington's poetry is the confluence of form and manner: his poems incline to classical verse schemes - sonnets, quatrains, balanced stanzas - while his style is similarly lucid in voice, diction and image. This felicitous combination gives his poems the feel of poise, intelligence, grace and finish'.
