Tropes associated with her work:
- Real-Life Relative: She has acted alongside her real-life daughter Charlotte "Charlie" Hayes in several Big Finish Doctor Who "Companion Chronicles" audio dramas.
- The Runner-Up Takes It All: She finished runner-up in the 1964 televised talent contest Search For A Star. Today, the only reason anyone remembers the show is that it launched Padbury's career, and the winner has long since faded into obscurity.
- You Sound Familiar: In addition to reprising her role as Zoe for Big Finish Doctor Who, she has also voiced Lorraine Baynes in "Davros" and the Time Eater in "Chronoclasm".
