456 Club is a candid, conversational podcast from Mamamia hosted by Narelda Jacobs and Cathrine Mahoney, designed for women navigating their 40s, 50s and 60s. Styled like a warm, witty group chat among close friends, the show tackles the topics often left out of mainstream conversation: perimenopause and menopause, changing bodies, sex and dating later in life, ambition and career reinvention, motherhood and not-motherhood, and the realities of ageing. Blending humour with honesty, Narelda and Cathrine create a space that feels relatable rather than clinical, often bringing in expert voices and personal anecdotes to validate shared experiences. The tone is light-hearted yet emotionally resonant, appealing to Gen X and older Millennial women seeking connection, laughs, and practical insight into midlife issues rarely discussed elsewhere. Fans of Mamamia's broader ecosystem—including shows like Unleashed and Very Peri—will find 456 Club a natural fit, as it shares the network's focus on women's health, relationships, and unapologetic honesty about the messier, funnier sides of getting older.
