The Outback Nunataks are a series of bare rock nunataks and mountains which are distributed over an area about long by wide. The group lies south of Emlen Peaks of the Usarp Mountains and west of Monument Nunataks and upper Rennick Glacier, adjacent to the featureless interior plateau.
The Outback Nunataks were discovered by the United States Victoria Land Traverse party, 1959–60, and mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1959–64. They were so named by the Advisory Committee on Antarctic Names (US-ACAN) for their remote position at the posterior side of the large mountain belt that extends from the Ross Sea to the interior ice plateau.
The terrain to the west of the nunataks is a featureless expanse of the polar plateau.The Emlen Peaks of the Usarp Mountains and the Helliwell Hills are to the north.The Rennick Glacier, the Freyberg Mountains, the Monument Nunataks and the Mesa Range are to the east.The Rennick Névé and the Sequence Hills are to the south.
Northwestern features include Mount Southard, Welcome Mountain, De Camp Nunatak, The Office Girls, Oona Cliff, Mount Walton, Mount Chadwick and Coleman Bluffs.

Southard, Chief, Office of International Activities, USGS, with responsibility for USGS field parties working in Antarctica; later Chief of the Topograpic Division of USGS.

Discovered by the United States Victoria Land Traverse Party, 1959-60. Louis J. Roberts, USGS surveyor with this party, proposed the name "Flattop Mountain," but to avoid duplication the US-ACAN named it for Roberts who was first to survey the feature.
