Brendan Shacklock is a highly experienced physical performance coach with over a decade of experience working across a wide range of sports and performance environments. Throughout his career, Brendan has coached athletes from amateur through to professional level, while also delivering impactful programs for the general public and disengaged youth.
Brendan’s career began at one of Melbourne’s leading sports academy schools, Box Hill Senior Secondary College, where he completed his early apprenticeship in strength and conditioning. He later relocated interstate to oversee the Strength and Conditioning Coaching Department at the University of Queensland, further expanding his expertise in elite performance environments.
Following this, Brendan spent several years working in professional sport across AFL, Rugby Union, and Football, holding senior performance roles within several of Australia’s most respected sporting organisations.
In recent years, Brendan has returned to the space where his journey first began—high school fitness and athletic development. He is deeply passionate about engaging and inspiring the next generation of high achievers, helping students develop the physical capacity, confidence, and habits required to perform at their best.
Brendan and his team are driven by the belief that high-quality strength and conditioning services should be accessible to everyone—not just those who can afford private coaching. He strongly advocates for exercise and physical development to be embedded in the environments where people spend the majority of their time: schools and workplaces.
This philosophy led to the creation of Next Phase Performance, a company focused on delivering industry-leading fitness, performance, and wellbeing services to students, student-athletes, and employees across South-East Queensland.
