Morris began her solo career with the single, "Puberty Blues" in December 1981 on Mushroom Records; it was the title track from the 1981 film "Puberty Blues", which was a local box-office success. The song was written by Tim Finn and performed by Sharon O'Neill in the film. The B-side was "Adolescent Angst", which Morris recorded with The Morris Majors. "Puberty Blues" reached the Australian Kent Music Report Singles Chart top 100. The follow-up single, "Little By Little"—a cover of The Springfields 1960's song—was released in 1982 but failed to chart.
