The available information for a voice actor named Cleo Paskell, including for the role of Betty in Adventures of the Little Koala, corresponds to a public figure named Cleo Paskal. While details on a sustained voice acting career are minimal, her early work includes that specific voice role, after which she transitioned to a career as a writer, journalist, and geopolitical analyst.

Cleo Paskal provided the English voice for the character Betty in the anime series Adventures of the Little Koala. The English-language adaptation of the show, which originally aired in 1987, was produced by CINAR. At the time of recording, Paskal was a child or young teenager, part of a trend in this particular dub where child actors were used to voice the young characters. Her involvement in the project represents her sole credited voice acting role. Beyond this, her on-screen acting credits are limited to a minor role in the 1976 film East End Hustle.

Following her early work in front of the camera and microphone, Paskal's professional focus shifted dramatically. She became an award-winning journalist and a writer, contributing to a wide array of publications including The Economist, The Independent, The Sunday Times, and the National Post. Her writing credits also extend to television, where she was a co-writer for the Primetime Emmy Award-winning documentary series Cirque du Soleil: Fire Within.

Her later career has been defined by expertise in geopolitics and strategic issues. She has held positions as an Associate Fellow at Chatham House and a Non-Resident Senior Fellow for the Indo-Pacific at the Foundation for Defense of Democracies. As an author and commentator, she has written extensively on environmental change and its security implications, earning numerous accolades for her written work in addition to her Emmy Award for television. Her professional background does not indicate any recurring collaborations with specific voice directors, studios, or other voice actors from her time on Adventures of the Little Koala.
