Trailblazing CEO, Defence Veteran & Champion for Social Change
Penelope Twemlow is a powerhouse of purpose, passion, and performance. With a remarkable career spanning defence, energy, business leadership, and social advocacy, she has become a highly sought-after keynote speaker who brings intellect, heart, and humour to every stage she steps on.
A Royal Australian Navy veteran with nearly eleven years of service, Penelope has since carved out an extraordinary career as a multi-award-winning CEO, businesswoman, mentor, and changemaker. She brings together deep expertise in leadership, risk, safety, and strategic transformation, with qualifications in everything from nuclear law and project management to health, safety and environment, policing, and investigations.
Penelope is known for leading complex programs across industries including defence, mining, aviation, energy, and utilities, often in high-stakes, high-pressure environments. But her most inspiring work comes from her commitment to social enterprise and advocacy. A passionate supporter of equity, diversity, mental health, domestic violence prevention, and homelessness, her impact was recognised with the 2016 Queensland Telstra Business Women’s Award for Social Enterprise.
Far more than a technical expert, Penelope is a people-first leader, collaborative, courageous, and capable of delivering meaningful change while empowering those around her. Whether you’re looking to ignite organisational transformation, support women in leadership, or unlock personal growth, Penelope delivers sharp insights and practical tools with charm, authenticity and razor-sharp wit.
