Perenjori was approved as the name of a siding in April 1913, and later that year the government decided to establish a townsite there.

In 1932, the Wheat Pool of Western Australia announced that the town would have two grain elevators, each fitted with an engine, installed at the railway siding.

A bulk wheat bin was constructed in the town in January 1940, which is capable of holding about 220,000 bushels.

The Lands Department approved agricultural lots of 1000 acres instead of the large pastoral leases which had been granted in the past.
