Bremer Island, or Dhambaliya in the local language is an island in the Arafura Sea, in the northwest of the Gulf of Carpentaria, 3.4 km off the northeast corner of Arnhem Land (Cape Wirawawoi), Northern Territory, Australia.

The town of Nhulunbuy lies five kilometers away on the mainland of Arnhem Land.

The only tourist facility is the small Banubanu Beach Retreat [1] at the northern tip of the island.

The island is surrounded by a beach, on which sea turtles dig their eggs into the sand.

4.5 km east of the island are the East Bremer Islets, a group of small rocky islets, including Higginson Island, which form the Higginson Important Bird Area.
