Under the nom de plume "Gallery Girl", Dreyer began writing theatre reviews for women's magazines.
Her scripts included "Story of a Lame Duck" (1951), an autobiographical account of living with a disability, and "Hard Way Back" (1953), which described the challenges faced by a recovering tuberculosis patient.
[1] The latter attracted controversy when it was denied permission to be broadcast after the Commonwealth Department of Health objected that it "over-emphasise[d] ... past the bounds of reality" the challenges experienced by patients (tuberculosis was considered a sensitive subject; a 1948 report by Maxwell Dunn had been suppressed on similar grounds).
[1] In 1959 she was joint winner (with Harry Fox) of the Walkley Award for Best Magazine Feature Story (Non-Fiction) for her article "The Day I Wiggled My Big Toe", published in New Idea.
[4] In the 1960s she co-authored three books with retired magistrate Arthur Debenham: Without Fear or Favour, All Manner of People and The Innocent Victims.
