[6][3][2] Elrundie consists of land associated with a peninsula known as the Elrundie Peninsula and part of the channels of the following waterbodies that bound the peninsula's coastline: the Hudson Creek to the north-west, the Elizabeth River to the south-west and the Myrmidon Creek to the south-east.

[1][10] The name is derived from Elrundie Flat, a name which is considered to be of Aboriginal origin and which was first used in 1869 in a document prepared by A.J.

Mitchell, a member of the Goyder expedition to the Northern Territory.

[5][3][11] The 2016 Australian census which was conducted in August 2016 reports that Elrundie had no people living within its boundaries.

[4] Elrundie is located within the federal division of Solomon, the territory electoral division of Spillett and part of the unincorporated areas of the Northern Territory.
