The Extremely Long Lunch is One in Five's signature annual fundraising event, bringing together community leaders, corporate partners, researchers, advocates and supporters for an unforgettable afternoon of connection, inspiration and impact.

Held in the iconic Olympic Room at the MCG, guests enjoy a premium long lunch experience featuring exceptional food and wine, entertainment, inspiring speakers, auctions, raffles and powerful stories that highlight the importance of mental health research.

Since its inception, the Extremely Long Lunch has helped raise significant funds to support groundbreaking medical research into mental illness, including depression and suicide prevention, eating disorders, women's mental health and other complex mental health conditions.

More than a fundraising event, the Extremely Long Lunch is an opportunity to come together as a community, celebrate hope, honour those affected by mental illness, and invest in research that has the power to change and save lives.

Past event

Mental illness is one of the leading causes of disability in Australia, and in many cases, it can have devastating impacts. Despite the growing need, medical research into mental illness remains severely underfunded. More support is needed to drive the breakthroughs we urgently need.

This August, we invite you to step up for medical research into mental illness. Whether you walk in honour of a loved one or for better mental health outcomes, your help will move us towards a future where mental illness is better understood, more effectively treated, and ultimately cured. Let's make a difference together!

Depression in women in their mid-40’s to early 50’s is a significant problem. An estimated 40% of perimenopausal women present to their primary healthcare physicians with depressive symptoms. Not coincidentally, suicide rates for women are highest in the 45–64 age group. 

One in Five have partnered with HER Centre Australia to conduct new research to better understand and treat menopausal depression.

Join us for a sit-down lunch to raise funds for research into the mental effects of perimenopause and menopause.
