The mallee emu-wren is restricted to open mallee woodland with spinifex understory in north-western Victoria and south-eastern South Australia. This region is rich in Triodia or as it is commonly known spinifex. The spinifex grass often grows to 1 metre (3 feet 3 inches) in height and provides the optimal habitat for the mallee emu-wren. [9]
The common name of the genus is derived from the resemblance of their tails to the feathers of an emu. [2] The genus was defined by French naturalist René Lesson in 1831 after his visit to Port Jackson on the 1823-5 voyage of the Coquille, although the southern emu-wren had already been encountered and described soon after European settlement at Sydney Cove.

The term is also applied to a vegetation association where these mallee eucalypts grow, on land that is generally flat without hills or tall trees and where the climate is semi-arid. [4] [5] Of the 32 Major Vegetation Groups classified under the National Vegetation Information System, "Mallee Woodlands and Shrublands" (MVG14):
Commonly known as the Mount Lofty Ranges Southern Emu-wren (MLSREW [13]), it is an endangered species under both the EPBC Act (Cwth) and the National Parks and Wildlife Act 1972 (SA). Its largest population inhabits the swamplands of the lower Finniss River , estimated to be 52–100 individuals, while fewer than 50 have been observed in Deep ...
The term Wimmera Mallee has also been used by the federal member for Mallee to describe their electorate, as the electorate covers both regions more-or-less in their entirety. The Mallee is sometimes referred to as an economic region, [19] of the Australian state of Victoria. The district is located entirely within the Victorian government's ...
In the late 1960s, morphological studies began to suggest that the Australo-Papuan fairywrens, the grasswrens, emu-wrens and two monotypic wren-like genera from New Guinea were related and, following Charles Sibley's pioneering work on egg-white proteins in the mid-1970s, Australian researchers adopted the family name Maluridae in 1975.

Also named the turquoise wren. It is found in mulga and mallee country across much of South Australia and the southern Northern Territory. It has lighter blue or turquoise upperparts than the splendid fairywren, as well as a black rump. Black-backed fairywren (M. s. melanotus) – Gould, 1841: Originally described as a separate species.
