Community concern is growing as the sale of a piece of land once set aside as a school site looms.
A for sale sign is on and a fence around three hectares of land at 98 Garside Road, Mollymook.
Conservation groups like the National Parks Association Milton Branch and Ulladulla based environmental group Knitting Nannas are both leading the call to have the sale stopped.
"Grab a big sheet of cardboard and some marking pens and make some signs," National Parks Association Milton Branch said in an online statement.
"The fence needs lots of signs [large or small] attached to it so the public can get stirred up about it.
"Signs could say "Don't sell public land" or "Stop the sale" or "Save our bushland" or just "Shame" or any protest you can think of. It doesn't matter if signs are repeated, we've just got to get them there - and quickly."
The groups are hoping a similar community-driven flight like the one in Manyana will form.
The land is listed for auction on Wednesday March 10 in Wollongong.
Knitting Nannas members will meet on-site this Wednesday, February 10 afternoon at 4pm to help community members set up the signs.
They stress it's not a protest rally.
Knitting Nannas says there was a lack of community consultation.
"I've looked on the Crown Land website and could find no reference to the parcel of land in the latest notifications and decisions," a Knitting Nannas spokesperson said.
"I did find a reference to a Community Engagement Strategy which outlines engagement requirements for seven items, including sales.
"Has there been a community engagement process for this parcel of land and if not, why not?
"Given the destruction of so much forest in Shoalhaven during last summer's fires, around 80 percent of the LGA was burnt, and the vital need for habitat refuges, was the parcel of land subject to an environmental assessment?"
Shoalhaven City Council's assessment of the proposed subdivision of the site in 2017 expressed concern about "comprehensive clearing, removal of hollow-bearing trees or any future clearing" of the site primarily because of its value for powerful owls.
More to come.
