Exercise Physiologists in Sydney

Hi @"Patti J" - I'm about to start Chemo and I'm totally unfit. I haven't done any real exercise for an incredibly long time. I want to do something positive throughout all of this treatment, try to lose some weight if that's possible and get exercising - so I'd love to get the advice of an exercise physiologist. I know that all I probably need to do is to start walking - cheap and cheerful! I would like to find out about working with weights though, and I've had a full node clearance on one side + a double mastectomy with expanders in also I'm insulin resistant and have an osteo-arthritic knee with lots of other areas of wear and tear.  So I'd prefer to get advice from someone who's worked with Breast Cancer people before rather than just someone at the local gym or any run of the mill personal trainer.
