Fish avoid a shark near Heron Island, Australia

The waters surrounding Heron Island, off the coast of Australia, beckon divers interested in up-close encounters with marine life in the Great Barrier Reef. Blacktip and lemon sharks swim here, and though they’re not considered aggressive around humans, they are formidable beasts. This shoal of fish parts to allow a shark to pass through: It’s not on the hunt, but the prey-sized fish are not taking any chances.


Heron Island is a coral cay located near the Tropic of Capricorn in the southern Great Barrier Reef, 80 km north-east of Gladstone, Queensland, Australia, and 460 km north-north-west of the state capital Brisbane. The island is situated on the leeward side of Heron Reef, a fringing platform reef of significant biodiversity, supporting around 900 of the 1,500 fish species and 72% of the coral species found on the Great Barrier Reef.
