We’ve got you covered.

Starting with the largest fitness facilities in Western Sydney, kitted out with modern, state of the art equipment, private fitness studios, saunas, a cafe and a crèche. (BTW, have you seen how many Group Fitness classes we run?)


Whether you want to find muscles you never knew you had, lose weight you thought you’d never be rid of or break a record on your bucket list, we know how to get you on your way. To top it off, our team of personal trainers and staff are here to help, support, and motivate – but never intimidate. At ONE55 we’ve got your back.


Our members have the advantage of having the SGAC on site. And what a huge presence it is – offering extensive aquatics programs, gymnastic classes and events, as well as Sydney West Sports Medicine, a large multi-disciplinary facility providing services that enhance health, well-being and rehabilitation.

We always welcome new-comers to the tribe.

Why not come down for a look around?
