Jill is originally from England but has spent the last 20 years living and working in France, Egypt, Peru and Australia. While pursuing a successful career in business she also maintained a passion for writing, teaching and drama, and after training as an actor with the Victoria College of Arts, she began producing scripts for one-act plays.

Jill's interest in children's fiction started with stories for her own children and grew through teaching French to Australian primary school children, and supporting reading schemes for young refugees. Inspired by a cartoon her son drew when he was a child, The Worm Who Knew Karate is Jill's first picture book. She is currently working on a number of new projects, including a series for first readers.
