About The Butterfly Effect

Did you know that Over 1 million Australians are living with an eating disorder and less than a quarter of them receive treatment or support?

The Butterfly Effect started out in 2016 as a female only fitness competition that was designed to provide a platform to raise awareness against negative body image and eating disorders. 

Throughout the years, we have witnessed the incredible power of women resonating with our message of “Celebrate Your Body”. As a result, the Butterfly Effect has become the Worlds leading female-only fitness festival. 

But we are not just about the competition; we are about creating a movement of women worldwide. We want to bring together a fitness community that focuses on what our bodies are capable of, rather than what we look like.

Experience the biggest celebration of female movement with the Butterfly Effect! In our ninth season in 2024, we are bringing you 14 incredible events, held across 3 countries that promise to be the highlight of the year. The Butterfly Effect competition is now an all-female Team of 3, with a new and exciting format.


Your Team of 3 will compete in 3 or 4 workouts, in a 1 day competition. The workouts will be released in May 2024. This allows participants to prepare and strategize, bringing their best to the event. The workouts are designed to challenge and showcase the strengths of each team, ensuring an exhilarating and fair competition.

In proud support of the Butterfly Foundation, $10 of every registration sold is donated to help fund vital programs and services. The Butterfly Foundation works tirelessly to support those affected by eating disorders and raise awareness about body positivity and mental health. By participating in the Butterfly Effect, you are not only challenging yourself physically but also contributing to a worthy cause.

So, its time to gather your squad and form a team of three. Whether you’re a beginner, intermediate, or advanced athlete, we have divisions that cater to all skill levels


Please check out our Movement Guidelines table located in the Athlete Tab in our Menu Bar. This will give you a good indication of the weights and movements that maybe required in the workouts. Don’t worry if you are not sure. If you need to change divisions once the workouts are released that is not a problem


Registration for a team of 3 is only AUD $299 / New Zealand Dollar $324 / British Pound £156.

Don’t miss out on this amazing opportunity to challenge yourself, support a worthy cause, and be part of the biggest celebration of the female movement – the Butterfly Effect!
