After graduating from the National Institute of Dramatic Art, Stephenson moved to Los Angeles, where she filmed a pilot for MTV.
[7] Stephenson appeared in the television drama Revenge from 2013 to 2014 as Sara Munello, the former girlfriend of main character Daniel Grayson (Josh Bowman).
[3] Stephenson recalled that she and Bowman had good chemistry during her audition, which she put down to them both being British and learning that their aunts are best friends.
[2] After filming Pray for Rain alongside Jane Seymour in 2017, Stephenson returned to Australia, where she was cast as widow Laura Maney in Tidelands, the first original Australian drama series for Netflix.
[10] Stephenson was reunited with her childhood friend Tim Franklin, who plays Taylor's love interest Colby Thorne.
The pair had not worked together before, and Stephenson told Kerry Harvey of Stuff.co.nz that they had often joked about how funny it would be if they became romantically involved on-screen.
