Welcome to The Bunker

The Bunker is a gym concept unlike anything seen in Australia. The hidden boutique studio is the brainchild of Justin Ashley and Serra Burmin, founders of the innovative One Playground. Justin and Serra’s mission is to push the boundaries of what people expect from the gym environment and experience.


What makes The Bunker different?

Community first

The facility’s award-winning, but it’s the community that keeps people coming. Membership numbers are kept low – as well as helping create a small, connected community, this means no waiting for equipment!

Inspiring space

The Bunker doesn’t look like your typical gym – every design element has been considered to create a space that inspires you to train at your best, in every session. An environment designed to help you focus.


No matter your goal, we’re serious about your results. We have Australia’s best-educated personal trainers. The best equipment, sourced from around the globe. And small-group, outcome-driven classes.

Premium affordability

Despite the quality of the fit-out, equipment, experiences and personal trainers, The Bunker membership is incredible value, starting at just $29.95 p/wk, making it accessible to all. And The Bunker members can access One Playground’s other clubs.

Not your average gym

We have always wondered why most gyms look and feel the same. After all, your environment drives motivation, and motivation drives results, right?

We made sure The Bunker is like no other gym. A place you want to be in, where people can use the best equipment in the world, try new fitness techniques, train to the latest beats and feel inspired.

I’ve been training at Fitness Playground and the Bunker for over 18 months now. Apart from strength training, I’ve loved working on improving callisthenics skills with my trainer Dave Marsh. It’s really helped with mobility, movement and strength, and overall well being. What I love most about the Bunker is the sense of community. All of the trainers help create a supportive and friendly environment that makes going every day an enjoyable and rewarding experience. Thank you for helping me become a better, and stronger me.

This gym has changed my life this year. Joined straight after the first lockdown and attended the group classes regularly. The variety of workouts provided has been better than any gym I've attended in the past and I've noticed much greater results than I've seen after years and years of gym training. The culture in the gym is fun and it's like working out with mates, music is always pumping and the trainers are great fun also.

The absolute best gym in Sydney. I'm currently living in Dubai but the second I return, I will 100% rejoin the Bunker. The staff there were so insanely nice, it really helped Sydney feel like home (I'm Canadian). They created such an awesome community vibe, not only in but outside of the gym too. Their classes were incredible, and their support around the gym was greatly appreciated as well. I miss you guys so much!

I have been training here for a year after trying 3 other gyms in the area and this was the first that made me feel comfortable and not intimidated. You guys have the BEST trainers working there, every time I am in they are saying hi always with a smile. Keep up the amazing work guys!
