Emma Johnston AO, the first woman to lead the University of Melbourne in its 172-year history, has died from complications with cancer at the age of 52. The university announced her passing on Monday, describing her as a transformative science researcher and brilliant reformer.
Johnston took up the role of vice-chancellor in February 2025, returning to the institution where she completed her undergraduate and postgraduate degrees, as well as a doctorate in marine ecology. A world-leading marine biologist, she specialised in the ecological impacts of human activities on marine ecosystems and was a chief author of Australia’s most recent State of the Environment report.
Her extensive research included authoring 185 peer-reviewed journal articles and supervising more than 35 students. She was also remembered as an impactful communicator dedicated to her students. Her family said their heartbreak had been greatly comforted by the outpouring of love and respect for Johnston and her work.
University chancellor Jane Hansen said Johnston made a meaningful contribution despite her brief tenure. “Professor Johnston brought a tone of optimism and energy to our university, with her insight, experience and most of all her belief in all who are part of this community,” she said. “She had an unwavering commitment to our students.”
Johnston was a director of the CSIRO and the Great Barrier Reef Marine Park Authority, governor of the Ian Potter Foundation, and former president of Science and Technology Australia. She was made an officer of the Order of Australia in 2018 and elected a Fellow of the Australian Academy of Science in 2022.
Science and Technology Australia president Jas Chambers said Johnston set an example that would inspire many. “Emma’s influence and impact will be felt for years to come. She leaves a great legacy,” Chambers said. Education minister Jason Clare described her as “a real reformer”. The university will commemorate Johnston at a later time, with Michael Wesley continuing as acting vice-chancellor.
