Harriet Spark

Harriet Spark has worked on productions for ABC, PBS Nature, National Geographic and Disney+, and is directing her debut feature documentary, Seahorse School. She is drawn to intimate, character-led films that make complex ideas feel immediate, emotional and alive.

She began on the Great Barrier Reef as a scuba instructor and marine advocate, then moved into digital media at the Great Barrier Reef Marine Park Authority. Her 2016 social films for 1 Million Women showed early how far a well-told story can travel. She trained at AFTRS, worked as associate producer and safety diver on Secrets of the Octopus for National Geographic, and then joined the ABC's impact team.

With more than a decade underwater, Harriet works on open-circuit and closed-circuit rebreather systems and has led shoots in tropical and temperate waters worldwide, bringing ambitious sequences home safely from remote locations while keeping crews and contributors close.

An Emerging League Member of the International League of Conservation Photographers, she has collaborated with WWF, the Australian Conservation Foundation and The Nature Conservancy. Her work has appeared in The Guardian, Australian Geographic, Oceanographic and The Sydney Morning Herald. She co-founded Grumpy Turtle Films, a production company telling stories about the natural world.
