Costal Breathing assistance

Costal Breathing assistance Hey all — bit of a Hail Mary but just wondering if anyone here knows of a good speech therapist/ pathologist in Australia who teaches costal breathing to help with stuttering? I’ve heard really positive things about the McGuire Program, which focuses on this kind of breathing technique, but unfortunately it’s out of my budget at the moment. Hoping there might be someone more affordable (or covered by Medicare) who teaches similar methods. Any recommendations or experiences would be hugely appreciated — cheers!
