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 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 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'.
