Kate Constable was born in Sangringham, Melbourne (Victoria, Australia). When she was six-years-old, her family moved to Papua New Guinea where her father worked as a pilot.
Constable got her Arts/Law degree at Melborne University, then got a job at Warner Music. She started writing during these years.
She wrote several short-stories before becoming an author and after her first attempt at writing a novel she fell in love with the man that is now her husband. They have a daughter.
Constable's first official novel was The Singer of All Songs, in a trilogy called The Chanters of Tremaris. It was published in 2002, a few weeks after Constable's daughter was born.
