It’s a small chain called Derrimut Gym (real small like a handful in the north west of one state and obviously one country, Australia).
It’s big and caters to a lot of different trainers from boxing to Powerlifting to bodybuilding. Lots of squat racks and barbells is always nice tho no specialty bars.
Speaking of cool gyms and speciality (kinda) bars my most recent workout was at a gym called Doherty’s, in the city with my friends. The gym is located in old tunnels beneath one of the busier train stations in the city so you can hear the rumbling as trains go overhead. There’s a beat up old platform and an Eleiko Power Bar which kinda makes up for the poor ventilation. Great vibe about the place
