Morrison's family moved from England to Tasmania when she was three. Aged fifteen, she studied art at East Sydney Technical College, specialising in sculpture. Norman Lindsay encouraged her to do book illustration, which resulted in her first publication with Hans Christian Andersen’s fairy tales in Triad (1927). She illustrated the serial 'Little Bo’ by Madeleine Honey in Australian Childhood from 20 June 1930.

In 1929 Morrison and Mollie Horseman were the first female cartoonists appointed to the staff of Smith's Weekly. She was also doing humorous drawings for the Sporting and Dramatic Magazine and illustrations for the Sydney Mail. In Smith's, Morrison briefly drew theatrical caricatures for the series 'Highspots from the Shows' and illustrated some of Ken Slessor’s later verses. From the early forties, she drew cartoons for KG Murray's Man. Her work focused on sassy glamour girls that came to be known as 'The Morrison Girl'.

Morrison was an active member of the Black and White Artists’ Club and the only woman among 25 men who organised the 1937 Artists’ Ball. She also painted murals in Gordon, although all have now been painted over.

She continued to work as a freelance illustrator throughout the fifties before retiring due to illness. Her last known illustrations were for the children's book, You Can Draw a Kangaroo/The Poems Tell You What to Do by Ronald McCuaig and Isla Stuart published in the early sixties.
