The locality was named Grevillia by early settlers due to the surrounding area containing a large amount of silky oak trees (Grevillea robusta). Grevillia was dominated by the lumber industry during the mid to late 19th century. The prominent timber company Munro & Lever was based in Grevillia, and operated a sawmill there until it was destroyed by a fire in 1929. Logging operations continued in Grevillia until 1943.

A primary school, Grevillia Public School, served the local area from 1922 but was closed in 2010, as only 2 students were seeking enrolment at the start of the 2011 school year.
