Forrest is on the longest stretch of straight railway in the world, at 479 km (298 mi) from Nurina in Western Australia to Ooldea in South Australia.
The airstrip at Forrest was the overnight stop on the first scheduled passenger air service between Perth and Adelaide from 1929 to 1934, operated by West Australian Airways. The 18-room hostel provided a restaurant meal "worthy of any city hotel".
Forrest was named after Sir John Forrest, the explorer who became the first Premier of Western Australia.
