Actor Myles Pollard has pleaded in a video to his fellow Dunsborough residents to join him in a protest against a third petrol station from being developed in the town centre.
Residents have been campaigning against the store which was labelled a convenience store to bypass local planning schemes.
An application to build a third service station in Dunsborough's town centre has been rejected twice by planning authorities and will go before the State Administrative Tribunal for the second time on February 1.
In December, more than 700 people rallied at the site of a proposed petrol station in protest.
A second protest will take place at Lions Park in Dunsborough from 10am on Saturday, January 21.
