Drysdale Island is a large but low-lying island in the Wessel Islands group in the Northern Territory of Australia. It is long and up to wide. It measures in area.[1]
The only settlement is Yirringa, a small family Aboriginal outstation at the northeastern end.[2]
There are numerous small lakes within it which are easily accessed by the tide, some of which are submerged for prolonged periods of time.
The much smaller and uninhabited Yargara Island (little more than one square kilometre in area) lies directly north and is separated from it by a shallow, rocky channel wide. Its nearest neighbour to the south-west is Graham Island, separated by a 1600m (5,200feet) wide marine channel. The easternmost point of the island is called Dale Point.
