The award-winning author was born in Melbourne and grew up in New Guinea. Her years there during the 1950s and 1960s provide the background for her first novel, The Beloved. Annah started writing when she was 14, with bursts of poetry and short stories.
Annah worked in the airline industry for seven years, then trained for four years to become a practitioner of Traditional Chinese Medicine. Fascinated by energy in all its forms, she specialised in acupuncture. She and her family moved to the Sunshine Coast in the early 1990s, where she opened her own practice. A desire to convey the effects of emotions on disease to the lay-person led her to her first substantial work of writing, a non-fiction manual from the traditional Chinese medical perspective. In 2000, she wrote and published a short humorous biography, Frankly Speaking. In 2007, a 5000-word story, The Blood of Others, was purchased and published in Antipodes, the North American Journal of Australian Literature.
Annah's first book, The Beloved, won the 2011 Queensland Premier's Literary Award for an unpublished manuscript. In 2013, The Beloved was commended for the Fellowship of Australian Writers' Christina Stead Award, shortlisted for the Miles Franklin Award and won the Nita B Kibble Award. Annah's second novel, Last Day in the Dynamite Factory, was published by Picador in June 2015 and shortlisted in 2015 for the Readings Award for New Fiction. Annah and her husband divide their time between Queensland’s Sunshine Coast and beautiful Tasmania.
