A public rally will be held in Margaret River town this weekend aimed at raising awareness and support for the preservation of the Gnarabup coastline.
The Preserve Gnarabup action group will host the event at Reuther Park on Saturday, and group spokesperson Beth Carlessi said she hoped to see a strong turnout.
"We are hoping to see the community members, including past and present activists, gather in a show of solidarity to show their support for the preservation of Gnarabup," Ms Carlessi said.
"Preserve Gnarabup feels like this development along our precious coastline will change the "sense of place" for the community and cause irreversible damage to the fragile ecosystem and the Aboriginal heritage site - a gnamma hole - located on one of the lots."
Gnamma holes are natural cavities commonly found in hard rock which act as natural water tanks, and are replenished from underground stores and rainwater run-off.
As of Tuesday afternoon, the group's Change.org petition had garnered more than 19,400 signatures in support of halting progress on the planned Margaret River Westin Resort & Spa.
Ms Carlessi welcomed the attendance of everyone in the community, including those in support of the construction of the hotel.
"I would love for people who support the development to hear the history of these pieces of land and to hear about the concerns the group have surrounding fire safety, infrastructure, the view of the traditional owners, the flora and fauna, rising sea levels and so on," she said.
"Many people do not realise that the resort is only the beginning and that the other lots will also be developed with villas and housing."
