Her earliest work appeared in 1968 but she began writing seriously in 1975 when she joined a group of writers associated with Lionel Abrahams who at one stage called themselves the Circle of Eight.
This group gathered around Lionel Abrahams had included at various times the writers Anne Schuster, the Beat poet Sinclair Beilis, Basil Du Toit, Debbie Aarons, novelist, critic and editor Ivan Vladislavic, academic and publisher Shirley Pendlebury, Michael Gardiner, Francis Faller, and others.
Anne Kellas's first book of poetry, Poems from Mt Moono, was published by Shirley Pendlebury's Hippogriff Press in 1989.
In 1995 Anne Kellas and Giles Hugo had set up one of the first Australian online magazines, The Write Stuff, which they jointly edited.
In 2006 after the tragic death of the editors' younger son, the site, which included the "Showcase of Tasmanian Poets" was formally closed.
In 2017, her third collection, The White Room Poems, was shortlisted for the Margaret Scott Prize as part of the Tasmanian Premier's Literary awards.
