About Us
Meet Josh and Nathan Katz
Team Katz is the speaking and mentoring business of Australian Olympic Judoka brothers Josh and Nathan Katz. We deliver keynotes, workshops and ongoing mentoring for schools, sporting organisations and corporate teams, drawing on our experience of competing internationally, managing setbacks and working towards long-term goals.
Our sessions connect those experiences to the audience in front of us. For students, that means navigating change and balancing priorities. For sporting groups, it means preparation, learning and team support. For corporate teams, it means handling pressure and following through on shared goals.
Nathan Katz
Nathan Katz represented Australia in Judo at the Rio 2016 and Tokyo 2020 Olympic Games, reaching the round of 16 in Tokyo. He also won bronze at the Birmingham 2022 Commonwealth Games.
After retiring from international competition in 2023, Nathan moved into coaching and became one of Josh’s coaches. At the Glasgow 2026 Commonwealth Games, he supported Josh from the coaches corner as his younger brother won silver.
That move from athlete to coach gives Nathan a different perspective on progress: helping someone prepare, offering feedback and supporting them through the uncertainty of competition. In his speaking and mentoring, he draws on both roles to discuss consistent habits, responding to disappointment and contributing to the people around you.
Nathan has also taken part in the AIS–Lifeline Community Custodians program, supporting conversations about mental health and seeking help.
Josh Katz
Josh Katz represented Australia in Judo at the Rio 2016 and Paris 2024 Olympic Games. He won bronze at the Birmingham 2022 Commonwealth Games and silver at Glasgow 2026, where his brother Nathan was in his corner as coach.
Josh made his Olympic debut at 18, becoming Australia’s youngest male Olympic Judoka. His path back to the Games included injuries and the disappointment of missing qualification for Tokyo 2020. Returning at Paris 2024 gives him a grounded perspective on reassessing a goal, responding to setbacks and continuing when progress takes longer than expected.
Through Team Katz, Josh brings that experience to conversations about preparation, confidence and the daily choices behind a long-term ambition. His speaking and mentoring connects the demands of elite sport with the challenges students, athletes and working teams face in their own lives.
Josh has previously held a Mental Fitness Ambassador role for the Black Dog Institute, and holds a double degree in exercise and sport science and sport management.
