Not sure that is accurate.
I spoke to the guys on the rescue boat and there was a report of a kitesurfer out the reefs, but no missing rider.
I think it may have been a beach goer making a call to rescue and then not watching if the person came in or not.
The helicopter did come on a fly past so someone did call them up.
heres a couple of pics from triggs, with a couple from the surf comp, rescue boat headed back to port after a few minutes of chatting to the kiters it seems.
