You can use it to view upcoming group fitness sessions, login to the member portal where you can book group fitness sessions as well as update your details.

You can also receive alerts on news and events happening in your chosen area e.g. gym, swimming lessons, gymnastics or all.

On top of this you can also use the Cafe Coffee Card when you purchase hot drinks and after nine, get the tenth free.

Frequently Asked Questions

Why do I have to register to get the app?

We ask you to register primarily to know what part of ONE Casey you are interested in. This is so, when we send push notifications (messages to your phone), we only send you information on what you are interested in. We will not use your information for any other purpose.

I get the message 'Username or Password is Incorrect' when trying to login

Your username is the email address you provided when you joined as a member. If you are not sure what email address you used when you joined, please contact us and we can confirm this for you.

The default password is - YMCACasey
It is case sensitive. If you have changed the password but cannot remember the new one, contact us and we will reset your password.
If you are still not able to login, contact us and we will reset your account for you.

I get the message 'Your session has expired. Please try again' when trying to login

This generally means your account wasn't logged out of on a previous occasion and has expired after a set amount of time. To fix this, turn off your computer or phone and try again. if this does not work, try clearing the cache. Information on how to do this for different browsers and phones can be found at

I am being asked to pay for group fitness classes even though I am a member

This can be caused for a couple of reasons.

  1. Your membership has been cancelled or suspended.
  2. You joined at one centre and are trying to book a group fitness session at another ONE Casey centre. If this happens (and it shouldn't) the membership type you are on has not been set to work across all ONE Casey facilities.

To remedy any of these causes please call us and we will resolve the issue as quickly as possible.

If you experience any other issues, please let us know about them by emailing:
