Flora & fauna

Groote Eylandt and its vast archipelago supports such an incredible range of flora and fauna—including many endangered species—that it has been listed as an area of international significance for its conservation values.

The archipelago is home to some 900 species of plants, 14 species of mammal, 39 species of reptile and more than 83 bird species. Twelve threatened animal species thrive on Groote Eylandt, including the northern hopping mouse, the brush-tailed rabbit rat and the northern quoll, often called the most distinctive Australian quoll.

The warm Gulf waters surrounding the island are home to an amazing variety of marine life, including five species of turtle, sea snakes, dugong, mud crabs, whales, sharks and an abundance of fish.

The area is an internationally significant site for nesting marine turtles and colonial seabirds, especially the green turtle (endangered) and the hawksbill turtle (critically endangered). One area in the archipelago also protects more than 1% of the world’s roseate terns, a tropical seabird.


Unlike other parts of the Top End, there are no feral animals on the island, including the destructive cane toad, which has wiped out some species on the mainland.

That is thanks to careful conservation and quarantine management programs run by local Indigenous rangers, who work tirelessly to protect Groote’s unique flora and fauna from these threats. The rangers also protect turtle nesting sites, find and remove dangerous ghost nets from the ocean, manage weeds and trap feral cats.

Bird watchers and nature lovers are blown away by the immense diversity of flora and fauna living and growing within easy access of the lodge.
