A Brazilian Jiu-Jitsu academy is more than a place to train.
It’s where friendships are built, confidence grows, goals are achieved, and people show up for each other week after week.
If there’s ever something we can do better, we’d much rather have a pconversation than a goodbye. Your feedback helps us grow, just as training helps us grow on the mats.
Thank you to every member who chooses to spend part of their week with us. Your trust, loyalty, and support are what make ONYX more than just an academy, they make it a community.
We’re proud to be on this journey with you 🖤🥋

You already know you’ll feel better after training.
Stronger. Fitter. More confident. Less stressed.
The hardest part is walking through the door, but your future self will always be glad you did.
Stop waiting for the “perfect time.” Come in, train, and see what you’re capable of. 🥋

BJJ is about far more than submissions and medals.
It’s about building the confidence to stay calm under pressure, making good decisions in difficult situations, and knowing how to protect yourself and those around you when there are no other options.
The best self defence is always to avoid conflict, de escalate when possible, and get home safely. BJJ doesn’t teach people to look for fights, it teaches them how to think clearly, control their emotions, and use the minimum force necessary if they ever find themselves in danger.
For many of our members, the greatest benefit isn’t what happens on the mats - it’s the confidence they carry into everyday life.
If you’ve ever considered learning a skill that could improve your fitness, confidence, and personal safety, now is the perfect time to start.
🥋 Your future self may thank you.
Just wanted to clear up a few rumours… 😅

Some extra snaps from our grading night 📸
In 2023, Josh walked through our doors as a 15 year old high school student looking to learn Brazilian Jiu Jitsu.
Over the last few years, we’ve watched him grow not only as a grappler, but as a young man. Through school, exams, life, and everything in between, he kept showing up, kept learning, and kept putting in the work.
Last year he graduated high school.
This week, he achieved another major milestone and earned his blue belt 🥋
Blue belts aren’t given. They’re earned through consistency, perseverance, and countless hours on the mats. Josh has done exactly that.
We’re incredibly proud of you, Josh. Congratulations on a well deserved blue belt. This is only the beginning 👏
