7News article on the sighting:
I raced longboards at Yeppoon SC in the '80s as well as doing the 'Keppel Crippler' windsurfing marathons which started from Emu park.
Farnborough beach is a bit further north from Yeppoon. I checked it out a few times for wave sailing as it seems to get more swell in a SE wind. It always felt a bit 'sharky' to me, but crocks never crossed my mind in those days.
