I called fernwood (Rothwell) last year and it was pretty expensive sorry I cant remember the details exactly, I ended up going to the gym in Margate, its on Oxley Av about a block before Woolies, I think its called BodyWorks. It was good as you could pay fortnightly, there was no admin fee and for $5 a week you could use the child minding facilities as much as you liked. Oh and if you wanted to stop you just gave them 2 weeks notice and they would stop the direct debits. Oh and you could still have regular programming sessions with a personal trainer.

Good luck
