Memorial for top COVID expert Mary-Louise McLaws vandalised in North Sydney

A memorial for one of Australia’s top epidemiologists who helped the nation navigate the COVID-19 pandemic has been vandalised years after her death.

Mary-Louise McLaws died in August 2023 following a long battle with cancer and a renowned career as a professor of disease at the University of NSW (UNSW) and an adviser to the World Health Organisation (WHO).

She quickly became a household name across Australia by regularly appearing in media interviews during the pandemic, providing expert advice to Australians.

Among the lifelong honours — including being appointed as an Officer of the Order of Australia (AO) — was a memorial plaque and tree being erected to look over the Sydney Harbour Bridge in Mary Booth Reserve in Kirribilli, North Sydney .

However, one local on Wednesday shared images of McLaws’ memorial tree torn off near the base.

“So sad to see that someone decided to snap and destroy a beautiful, natural tree memorial to the late professor,” the local said in a social media post.

North Sydney Council told 7NEWS.com.au it was aware of the tree being “vandalised” and has “arranged for the tree to be replaced”.

McLaws had been diagnosed with a brain tumour in January 2022 after experiencing a headache, thanking Australians for their best wishes a month later.

“My treatment is underway. We are fortunate with our fabulous medical, nursing, cleaning and support groups,” she said in a post to social media.

“It has been my privilege, with the help of the media, to assist Australians during the pandemic through infection control,” McLaws said.

“Thank you for your support and for looking after each other. Remember, get a booster shot!”

Her death sent shockwaves through the worlds of science and politics, with former prime minister Malcolm Turnbull expressing his admiration.

“You spoke truth, you took on the pandemic of disinformation, you helped keep us safe, for that we owe you so much,” he said.

“From leading the charge to eliminate HIV, contain pandemics and helping stop the spread of swine flu,” he said.
