She has won the John Hinde Award for Science Fiction from the Australian Writers’ Guild; the Sir Peter Ustinov Award for Television Writing from the International Emmys; been nominated for two Australian Writers’ Guild Awards for ‘Best Feature Adaptation’ and ‘Best Animation’; and has been featured on the Black List, Hit List and Blood List for her original scripts.

Catherine’s feature THE OTHER LAMB held its world premiere at TIFF 2019 as a Special Presentation, garnering rave reviews, before going on to screen in competition at BFI London, San Sebastian, as well as at acclaimed genre-festival Fantastic Fest.

The Hollywood Reporter called it “a visionary tale… that hits the sweet spot between The Handmaid’s Tale and cult horror” and SlashFilm praised it as  “a fierce and striking depiction of resiliency… a screenplay that possesses a poignant relevancy which has reverberated throughout history.” Produced by Rumble Films (Drive, Whiplash, Nightcrawler), IFC Midnight released the film in 2020.

In TV, Catherine has worked as a writer, showrunner, and script editor in Australian and U.S. writers’ rooms, and has sold and set-up pilots with Netflix, NBC, Warner Bros., AMC, and eOne. She wrote the acclaimed anthology episode ‘Dream Of A Thousand Cats / Calliope’ on The Sandman S1 (Warner Bros / Netflix), subsequently nominated for a 2023 Australian Writers’ Guild Award; was a writer and consulting producer on Two Sentence Horror Stories (The CW/Netflix), writing the premiere pilot episode ‘Gentleman’ and ‘Tutorial’; and co-wrote an episode of Bloom S2 (Stan/Hulu).

She wrote the adaption of Wentworth VR (Foxtel), which won the Screen Producers Australia “Best Interactive or Game Production” 2018, as well as writing the original short Parked: The Carnival Of Secrets, supported by Screen Australia and YouTube, which currently has 4 million views.

Prior to becoming a screenwriter, Catherine has worked extensively as a production freelancer, and her professional credits include HBO’s The Leftovers, Syfy series Hunters and Childhood’s End, teen series Nowhere Boys, unscripted shows Real Housewives Of Melbourne and Formal Wars, and feature films Cut Snake and Paper Planes.

Her prose writing has been published in Nightmare Magazine, Aurealis Magazine, and Interzone, and reprinted in anthologies such as Year's Best Australian Fantasy & Horror and Focus: Highlights of Australian Short Fiction. Her short story 'The Nest' was nominated for a Shadows Award from the Australian Horror Writers' Association. She was the youngest person ever to sell a story to a professional science-fiction magazine, selling to Interzone at age 10.

She is currently in development on multiple projects, including a feature adaption of her own award-winning horror short story ‘The Nest’; a co-creator of Twisted, a series adaption of the works of iconic Australian author Paul Jennings; and a series adaption with producers Gale Anne Hurd and Phillip Kobylanski at Valhalla Motion Pictures (The Walking Dead). 

Catherine graduated with a double degree in Arts (Film Studies)/Law from the University of Melbourne, on a Melbourne National scholarship, and was a recipient of the Australian Government Students Prize.
