She is an Honorary Ambassador for the Museum of Contemporary Art Australia, a Director on the Australian Chamber Orchestra (ACO) Board, and an Advisory Board Member for Sydney Football Club. She has also served as Chairperson of the Australia Guizhou Chamber of Commerce for over a decade and is an official Ambassador for Guizhou tourism.
Her philanthropic commitment has been recognised with honours such as the Children’s Cancer Institute Benefactor Award and the Australia-China Alumni Award for Social Influence.
In addition to her cultural and philanthropic leadership, Monika is a highly sought-after brand ambassador for some of the world’s most prestigious names, including Sime Darby Motor Group, Diageo, Bang & Olufsen, and the Dorchester Collection’s Hotel Plaza Athénée.
