2026 Bonsai Open Demonstrators

  • Stephen Callum

    Stephen took up the hobby of bonsai more than 35 years ago but it was 2014 that he launched a second career teaching and demonstrating bonsai, with an ambition to influence the shape of Australian bonsai.

    His message since that time remains the defining character of Stephen’s bonsai practice today, to focus on a tree’s natural form as his principal styling reference. His particular interest is in the expression of a broadleaf bonsai aesthetic which is founded on an exploration of the authentic natural forms of broadleaf trees, backed up by the Japanese aesthetic principles of reverence of the natural world, respect of age and resilience. It is these ideas which provide both the substance and the boundaries to his design philosophy; to create bonsai that look and more importantly feel like trees.

    Stephen has embraced the use of Australian native species in bonsai and is well known for his advocacy of working with natives. He has trialled hundreds of species and his collection now comprises over 30 different genera and 50 species.

    As well as a bonsai enthusiast, demonstrator, teacher, and coach, he is also a maker of stoneware bonsai pots, and the author of Bonsai Foundations and Australian Native Bonsai: The essential knowledge to build better bonsai

  • Kim de Korte

    Kim de Korte (nee Rochelle-Brown) has been enjoying bonsai since 1992 as part of her teaching degrees in Japanese. She lived and worked in Tokyo in 1996, as part of her  scholarships, which gave her the opportunity to see and learn further about this wonderful art.

    Her mum had fruiting trees in Melbourne so bonsai have always been around her, with memories of oaks, crab apples, cedars and cold climate trees.

    She is a member of the Qld Bonsai Society and the Bonsai Clubs International. Kim has had ‘Lilliannah Bonsai’ since 2021 on the Gold Coast, Hope Island. Lilli and Hannah, her children (Lilliannah) was the perfect name for her bonsai business!

    She has demonstrated around Qld in bonsai clubs, corporate sectors for businesses, hospitals, aged care, City Councils, Garden Clubs, and in schools.

    Her favourite species are the Swamp Cypress for their impressive nebari, colours and the power of a large tree and Corky Bark Elms for their delicate leaves and textured bark.
