Consumer Affairs Victoria lists at least 5 of their practices and contract terms as being "unfair" - see file:///C:/Users/Admin/Downloads/Preventing%20unfair%20terms%20in%20health%20and%20fitness%20centre%20membership%20agreements%20(1).pdf
Try to wring every last dollar they possibly can from you by including unintelligible clauses into the contract. Wasn't allowed to pay 6-months upfront ... th ey want your credit card number so they can keep withdrawing money after membership expires by not 'accepting' cancellation of your membership unless you pay a further full month. Wasn't allowed to take the contract home to think about it, but was required to sign it on the spot.
The clause "Account Must Be Active And Not On Suspension When Cancelling All Payments in 30 Day Notice Period Must Be At Full Membership Rate" means that even if you try to cancel your membership 29 days before your membership expires, you'll be paying for another month. You're not allowed to write to them to cancel your membership, you must request a form, download it, fill it in, then upload or take it in to them AND THEN they need to approve it, but don't hold your breath.
OVERALL REVIEW - they hustle you at the start, then swindle you at the end. RECOMMENDATION - Avoid.
