To my knowledge, though take this with a grain of salt:
WAFM was the branding used under Redwave’s ownership of the North West Radio s.39 licenses - 6HED Broome/Port Hedland (sister of 6NW), 6GGG Geraldton (6BAY) and, oddly enough, 6RED Karratha (6KA) - as well as 6GGG Geraldton, formerly 6GE.
KA/NW/BAY became Spirit, aligned with 6SAT, and HED/GGG/RED were aligned with Red FM, albeit with separate branding. WAFM, by now a CHR station, was merged with Red FM in February 2015. Other than the latter, I can’t confirm the timeline of any of the above - nor whether, for example, 6SAT was branded as WAFM for a time.
