From an early age Kirsty Murray loved listening to all types of stories in the school yard and elsewhere. Her father, the sculptor Guy Boyd was a natural storyteller and her mother, Phyllis, was a passionate reader. Murray has made her home in a number of countries including France, Wales and North America; her Australian home is in Melbourne. Murray writes children's fiction with a focus on Australian history.
After working in a number of other fields, including graphic arts, Murray enrolled in Professional Writing and Editing at RMIT. She subsequently began writing non-fiction for younger readers. She turned to writing fiction in 1999 and developed a particular focus on Australian historical fiction. A member of the famous Boyd family, Murray is the great granddaughter of artist Emma Minnie Boyd, great niece of writer Martin Boyd and artist Penleigh Boyd and niece of the artists Arthur and David Boyd.
In 2012, Murray joined Benjamin Law and three Indian writers in the Bookwallah, an initiative which took the five across India by train on a kind of travelling library that took them between literary festivals.
