This was followed by her breakthrough role playing Sister Mary Amnesia in Tobie Cronje's production of Nunsense at the Alhambra Theatre in 1987, which garnered Normington her first Fleur du Cap Award for Best Actress in a Musical.

[3] She followed this successful turn with the Trilogy of '87 at the Durban Playhouse, where she performed a triple role as Joanna in Sweeney Todd, Niki in Sweet Charity, and also appeared in Candide, in a cycle in which all three productions were staged on the same day, one after the other.

Her first job in London was in the West End production of Sunset Boulevard in its initial run in 1993, which featured Patti LuPone as Norma Desmond, in which Normington understudied the role of Betty Schaefer.

More recently, Normington has had several star turns, as Mrs Shears and various other characters in The Curious Incident Of The Dog In the Night Time in 2018, as The Witch in PTP's Into the Woods in Cape Town and Johannesburg in 2019 (a role for which she was nominated for both Fleur du Cap and Naledi Awards), and as the Narrator in The Rocky Horror Show in 2020.

[16] Normington has also had a long and varied television career, appearing in many popular South African programs, such as Scandal, Shado's, Hard Copy, 7de Laan, The Lab, Backstage, and The Res.

[19] Normington has also released two solo albums, Mother's Daughter - for which she wrote six original tracks[20] - and a recording of Tell Me On a Sunday, the first act of Andrew Lloyd Webber's Song and Dance.
