Katie Johnston is a speaker, psychology graduate, life coach and media personality who captured Australia’s heart—and is now using her voice to help others reclaim their own.

When Katie first appeared on Channel 9’s Married At First Sight in 2025, audiences were drawn to her warmth, honesty and disarming charm. As A Current Affair host Alison Langdon put it, “When we first met Katie, we instantly fell in love with her warmth and kindness—even earning her the nickname, Australia’s sweetheart. Behind the smile was a heart-breaking secret, and Katie is finally ready to share it.”

Katie’s secret was the weight she had carried—not just physically, but emotionally. After surviving a sexual assault in her early 20s, Katie subconsciously gained weight as a form of self-protection. She wore her body like armour, hoping invisibility would mean safety.

Years later, she began to understand the trauma she had buried deep—and the patterns of self-sabotage that followed. Her healing journey led her to complete a degree in Behavioural Science (Psychology) and a Diploma in Life Coaching, arming her with tools to help herself and others.

Her story was told in a powerful8-minute A Current Affair feature that resonated with the nation, spiking ratings by more than 200,000 viewers over a normal night’s ratings. It cemented Katie’s status as a voice for every woman who has ever felt unseen, unheard, or unworthy.

Today, Katie is a sought-after speaker on trauma, body image, mental health, and the psychology of healing. Katie Johnston speaker and motivator blends lived experience with professional insight, helping women unlearn shame and reconnect with their self-worth—one conversation at a time.
