Ive seen em in the water while surfing only once at Flinders but at least 2 mile out and the only reason I knew it was them was the black and white colors spiining through the air as they flew.

LAst year we saw something unexplainable out about the same distance about eight round lumps all heading through the water together or maybe joined up underneath very simular to that footage of Lock ness monster with that series of lumps going along.
We thought it was boats at first like jet skis all going along together but slowly then they all sank,very strange.
