I have my daughter at Griffith uni CC. I don't think you have to go there to use it. It is an amazing centre and I visited them all in those areas you mentioned and briefly went to another until we found this one. There is a big centre at Tarragindi that we had our names down but it seems to be a long wait. Their facility looked excellent. Sorry can't remember the exact name. I wasn't fussed on any of the centres in mount gravatt and holland park. PM me if you need a hand. I am about to go to bed though!
