Early movement is not about performance — it’s about building strong foundations.
At ONYX, toddlers explore movement through play in a safe and pressure-free environment, developing coordination, confidence, and cognitive skills that support them far beyond gymnastics.
A strong start for any future sport 🩷

Meet Tanya, our new Head Coach 🤍
Hi, I’m Tanya — a Women’s Artistic Gymnastics Coach from the UK with 20 years of experience in the sport.
I’ve recently moved to Sydney with my husband, our two young daughters, and our golden retriever 🐾 and I’m so excited to be part of the Onyx family.
One of my proudest achievements has been guiding my gymnast, Freya Hill, to the British Championships for Disability Gymnastics for three consecutive years — an unforgettable journey.
My favourite skill to coach? Handstands. Once a gymnast masters a strong, technically sound handstand, everything else starts to fall into place.
I’m passionate about building strong foundations, developing great technique, and helping gymnasts grow into confident athletes who love the sport.
We’re so excited to have you at Onyx 💫

Meet Coach Jasmine!!
Jasmine grew up training State level WAG in the US for 10 years. After a short break in high school, she got back into it as soon as she could, joining her university’s gymnastics club. Her passion for the sport and love of working with kids made coaching the obvious next step! 💕
Having worked at Onyx for just over a year, Jasmine has had a wide range of coaching experience, including recreational, tumbling, and competitive classes. She focuses on helping gymnasts to achieve strong basics with good technique, while also having lots of fun 🎉
Jasmine is so excited to continue helping her gymnasts grow and learn, while nurturing the same love for the sport that she has. She coaches classes built on positivity, confidence, and fun, and looks forward to helping gymnasts achieve new skills in a safe environment 🤸🏻♀️🏅
