WHISE hosted a free forum on biological sex, gender, and mental wellbeing. It was designed specifically for those who sit in roles in health promotion, health planning, programming, and policy. In collaboration with the HER Centre Australia, this event represented the very first event under the new Gender and Mental Wellbeing portfolio for WHISE. It explored the biological determinants of women’s mental wellbeing across the lifespan, including but not limited to menstruation, pregnancy, birth, and menopause.
