Our Leadership


Thenu stepped up to be Oaktree's CEO in February 2021, bringing three years of experience in international and community development. Alongside her role at Oaktree, Thenu is currently completing her Juris Doctor at the University of Melbourne and working with the World Economic Forum's Global Shaper community. The proud daughter of Sri Lankan immigrants, Thenu’s belief in human rights, empathy and justice is unwavering. Thenu envisions a world where governments, civil society and the private sector can come together to provide innovative solutions to the most pressing issues of our time. In her spare time (she promises she has some), you can find her learning to Salsa Dance, re-reading Dan Brown books and defending her South Australian pronunciation of the word 'graph'.



Lucie started at Oaktree in early 2021, before transitioning into the role of Deputy CEO in October 2022. Alongside this, Lucie is currently studying a Bachelor of Arts (majoring in Politics and Asian Studies) at the University of Melbourne and working with the Sustainable Development Solutions Network Youth Advisory Group for the AusNZPac region. Having grown up in Hong Kong, she is passionate about bridging the divide between youth from different cultures and giving a voice to those with different points of view. Outside of the organisation, you can usually find Lucie attempting a new recipe in the kitchen, or working to master her proficiency in Mandarin Chinese.
