I've been at ONYX for approximately a year now. I've loved training here and plan to stay. As a female member, I briefly started in the females only class before transitioning to the mixed class and found that all the other members have been incredibly welcoming, respectful, and helpful. Professor Ian is a great coach who fosters a respectful and fun training environment. In class he is always present to help guide each student and ensure we've understood the techniques taught that day. I would definitely recommend ONYX to anyone interested in training BJJ regardless of experience.

My daughter has been training at Onyx for the past 5 years, and it has been an incredible journey. The coaches are knowledgeable, dedicated, and genuinely invested in every student’s growth. I’ve seen her skills, confidence, discipline, and fitness improve tremendously over the years. The progression through the program is well structured, and the support and encouragement from the entire team make a real difference. The environment is positive, welcoming, and motivating for students of all ages and abilities. Thank you to everyone at Onyx for your commitment and for helping my daughter grow both in the sport and as a person. I highly recommend Onyx to anyone looking for a supportive and professional training environment.

Great experience for my 6 yr old to start learning life lessons in protecting herself. We love the family atmosphere and the instructor who has patience for beginners. I recommend them for anyone that is thinking to join their kids up in the arts.

I have been training at ONXY with my daughter for almost 4 years now. We still love training there every week. Professor Ian has been nothing but professional, friendly and encouraging. It was nerve wracking doing jiu jitsu as a female, but everyone on the mat are so kind and respectful. They use high quality mats and disinfected every day. A safe place for female and kids to train at.

My son and I had been training at another gym before deciding to make the switch to Onyx after hearing so many great things from friends. From the moment we walked through the doors, we knew this was where we wanted to train. Everyone made us feel welcome from day one, and the supportive, family-friendly culture has kept me coming back every week for almost three years. Professor Ian's knowledge, passion, and dedication to teaching Jiu-Jitsu are second to none. He genuinely cares about every student and is always happy to stay back after class to answer questions, help with techniques, or offer extra guidance. He never makes you feel rushed and is invested in helping everyone improve, no matter their experience level. If you're looking for a gym with outstanding coaching, a welcoming community, and a great environment for both adults and kids, I can't recommend Onyx highly enough.

Fantastic gym with a great culture and high-quality coaching. What stands out most is the professor’s integrity. He genuinely puts his students and the team first, and it shows in the positive environment he’s built. Highly recommend to anyone looking to train BJJ.

Couldn’t recommend ONYX enough! The environment is incredibly welcoming from the moment you walk in. Tilly at the front desk who is always so friendly and welcoming which creates such a positive introduction to the gym. Then Professor Ian who is fantastic—especially with kids. He’s patient, encouraging, and knows exactly how to build their confidence while keeping classes fun and engaging! You can tell he has such dedication to the sport and his students. The gym has a great community and has been so welcoming to our family. Thanks again ONYX!

ONYX BJJ is truly a home away from home. Professor Ian is incredibly knowledgeable and welcoming to everyone. The team spirit is infectious. We all respect each other and focus on growing together. This is a judgment-free zone. If you're thinking about starting BJJ, walking through those doors is the best decision you can make!

I had a great experience there doing the Tuesday 11am class! My local Jiuy gym is based in the Northern Beaches and it felt at home rolling with the Onyx family in Campbelltown Professor Ian went through 3 variations in open guard and I learnt some very handy tips and tricks to help my Jiuy grow. I’m only a white belt but this is the reason I’m happy to be on the Jiuy journey learning new things every class…. OOOOSSSSSAH

Coaches are knowledgeable and students are friendly, with a great culture. Classes are well organised with clear, practical instruction. Mats are spotless and the gym is tidy. Thanks for the awesome training. I look forward to coming back for more training.

Really great gym. Professor Ian has been really great with our son. He’s been attentive, streamlined, knowledgeable and playful where needed. There seems to be a really good attitude and atmosphere amongst the children, especially those in the older classes who have been coming for some time. Classes are a little more expensive than some places but understand you’re under good care and I believe the expertise of a black belt. Worth trying to see if it is a good fit for you or your family.
