[2][3] The Wilmington-Ucolta Road passes through here, intersecting with the RM Williams Way which leads to the Birdsville and Oodnadatta Tracks.

Prior to European settlement, Orroroo was the home of the Ngadjuri Aboriginal people whose domain was the area to the east of the Flinders Rangers.

The name was first used by an early pioneer who conducted a nearby coaching house which served travellers on the Burra-Blinman track.

Charlie Easther settled in Orroroo during 1864 and opened up an eating house that became a popular stopping point for the drovers and bullockies who travelled through the area.

On 24 August 1923, 230-volt electricity was connected to the town by Cr Martin Redden, Chairman of the District Council, in the presence of a large crowd.

[7] Orroroo is the service centre for a predominantly farming community with the main products being wheat, sheep, cattle, pigs and a kangaroo processor.

[8] The town was connected by the Peterborough–Quorn railway line to Peterborough and Quorn in September 1881, and was served by a Class 1 station and a large Goods Shed.

[9] Steamtown, a railway preservation group based at Peterborough, operated passenger trains for tourists to Orroroo and Eurelia until 2002.
