A visitor to the island sent in photos and videos showing packs of dingoes walking about the island, which also showed them walking around quite closely to people on the beach.

"I found that there was an over presence of dingo packs this holiday season," Andrew Richter told ABC News.

In July 2017, a 25-year-old woman suffered minor injuries after being bitten on the arm by a dingo at Lake Mackenzie near the centre of the island.
