The philanthropy, academic and environmental sectors are mourning the unexpected loss of Professor Emma Johnston AO, a leading marine scientist and university educator. Tributes paid by sector leaders this week praised her leadership, intellect and generosity, which shaped some of Australia’s most significant conservation and sector strengthening initiatives.
In her role as Vice-Chancellor at the University of Melbourne, and across her career in leadership roles at organisations including University New South Wales, the Sydney Institute of Marine Science, and Science & Technology Australia, Professor Johnston brought her scientific expertise directly into philanthropic practice.
Professor Johnston established and ran the Sydney Harbour Research program and was made an Officer of the Order of Australia (AO) in 2018 for her service to scientific institutes and higher education, particularly to marine ecology.
In a tribute published on LinkedIn, The Ian Potter Foundation, where she was Governor, recognised her contribution.
“As a Governor of The Ian Potter Foundation and Chair of its Environment Committee, she played a major role in refining the Foundation’s environmental strategy and championing work that will have a long-lasting national impact. During her tenure, she strongly supported the establishment of the Biodiversity Council, ongoing investment in the Invasive Species Council, and the Warddeken Indigenous Rangers project in the Northern Territory.”
The Ian Potter Foundation noted that her energy, wisdom and unwavering commitment to protecting Australia’s natural environment inspired everyone who worked with her. They said her contributions will continue to shape conservation efforts for many years.
Reflecting on Professor Johnston’s passing, Harriet McCallum, Executive Officer of Mannifera, described Emma as “the strongest force, with a huge heart and brilliant mind”. She said Emma’s legacy lives on across public institutions and the environmental sector.
In honour of her lifelong dedication to protecting ecosystems, Professor Johnston’s family has established the Professor Emma Johnston Fund at Australian Communities Foundation (DGR1). The Fund will support research in marine ecology and help strengthen the resilience of at-risk ecosystems.
