Copacabana locals have voiced their concerns to Council, over works to construct a permanent pathway between the headland and Winney Bay.
Contractors have been clearing vegetation to make way for the path between the isolated beach and the Captain Cook lookout, as part of the 5 Lands Coastal Walkway masterplan.
It's got locals like Heather Graham worried about the effects constructing a wide path will have on native flora and fauna.
"The area has several threatened species," Ms Graham says "That's my main concern, there also appeared to be cement around trees, and on a later walk I noticed there was also asbestos in some of the fill surrounding construction."

However, 5 Lands Walk committee member Adam Richards says the land will be rehabilitated, and argues the works will actually have a positive environmental impact.
"When you are going to build something you have to do some preparation work," Mr Richards says.
"The Council guys have been up there and stripped back the top soil. So right now it looks a bit bare... but I'm 100% certain that once the pathway is finished, the rehabilitation phase will begin and it'll all grow back within a couple of years."
Ms Graham also claims the initial consultations weren't highly publicised.
"There was consultation in 2010 and 2011, (but) I've spoken to a lot of long-term Copacabana locals, and none of them appear to have heard of it."
A group of concerned residents have asked Council for copies of the masterplan, environmental and Indigenous heritage reports in recent weeks.

Mr Richards says the initial consultations were sufficient, but is happy for further sessions to be held to update the community.
