Musette Morell wrote for radio, mostly plays, but also for the ABC children's session, and for the New South Wales School Magazine. Contemporary newspapers said of her in 1940:
Musette Morell is an Australian girl, of the fourth generation, of mixed Spanish and Irish blood— a potent mixture. Even as a child she I was literary. At 16 she had written lyrics to music, published by Chappie and Co. Since then she has written many children's verses and stories for "The Bulletin" and for the magazines, and she is the author of several radio plays, three of which have, been produced by the A.B.C. Quite an author. ('Turn on the Wireless', Daily Examiner, 10 January 1940, p.6.)
Morell is mentioned in correspondence between Miles Franklin and Katharine Susannah PrichardS$), qq.v. (Letters reproduced in As Good as a Yarn with You, 1992, edited by Carole Ferrier u%23)q.v.). In a letter to Franklin dated 5 March 1950, Prichard said that she admired Morell 'for her spirit and fortitude. I like her work too - its originality and verve.' When Morell died, Franklin wrote that 'her going leaves not only a gap but a wound. She was one of the few who bothered about me. She was always exhorting me, even went so far as to send me an eraser and paper and a type-ribbon, and threatened me with a byro pen-pencil...' (Franklin to Prichard 28 December 1950).
