Tiger sharks would have the toughest teeth of all – smaller than those of a white pointer and with an unusual three-sided shape.
This shark was believed to be \highly territorial\ at this remote location. It made several fast rushes at the small group of divers and snorkellers.
The shark apparently resented the wet suited invaders entering its territory.
No injuries occured but it was a very anxious time for those concerned. The swim fins belonged to **Roy Bisson** the art director at **Fathom** magazine.
Dr Richard Ibara captured the sequence on 16mm. It appears in the documentary film \**Australian Seafari**.\
