It is located on the Great Eastern Highway and the railway line from Northam to Southern Cross. When the line was opened in 1895 a railway station was established here and named Parkers Road after a nearby road. The road led to Parker Range, an area where Mr W M Parker made a gold find in 1888. In 1923 the district surveyor for the area reported there was a need to survey some lots at Parkers Road station. The survey was carried out the following year, and in 1925 the area was gazetted as the townsite of Parker Road.
Name
In 1926 the local member of Parliament advised the name of the townsite was causing confusion because it was too similar to Parker Range, a nearby goldmining area, and was also the name of a road in Southern Cross. He suggested the alternative name of Moorine, after Moorine Rock. This name was too similar to Moora, but was accepted with the full name Moorine Rock. The change of name of the townsite was gazetted in 1926. Moorine Rock is the Aboriginal name of some rocks near the townsite, first recorded by an explorer in 1865. The meaning of the name is not known.
