About Us

Onyx Gymnastics is a gymnastics club in Sydney’s lower North Shore. Working exclusively with individuals and small groups, experienced coach Alexandra Leeder has developed a nurture-based pathway to gymnastics success.

At Onyx, we focus on the unique development of every gymnast and the wellbeing of our students is at the heart of everything we do.

Everyone can benefit from a positive fitness environment and our experience tells us that it is particularly important for gymnasts. Young children thrive when given the tools and opportunity to work in a fun but focussed environment. Adults gain confidence and body-positivity when learning how to control and move their body in new ways.

Please see here for more information about the classes we offer or contact us for more information.

We’re conveniently located down at Middle head in Mosman. We have two exclusive venues (that includes air conditioning!). If you’re interested in what we offer, please come and visit our space!
