Seems Norfolk Island has the biggest Tiger Sharks by size in the world. With growth up to 4m in length, a full metre more than the world average of 3m.
The myth of the islanders dumping cattle remains off a cliff being the main culprit, but a 3 year research proved that it only contributed to 10% of its diet and sea birds being the biggest contributer with 40 birds found in the stomach of one specimen. Fish and other water species, being the remainder of their diet.
