The resident says the foreshore along Mollymook and Rennies Beaches are overgrown and unsightly and in need of urgent work.

"I have been in contact with our council quite a bit regarding this but pretty much to no avail," he said.

"Is anyone concerned about the current upkeep and overgrowth of our beaches?

"Especially Mollymook and Rennies beach as both are the premier beaches in the Shoalhaven region with thousands of visitors and locals experiencing their beauty daily."

Apart from being unsightly, the overgrown foreshores are attracting vermin.

"The two seemed to have been poorly neglected and the growth is unsightly and becoming dangerous," he said.

"The wayward trees with low branches have affected the access stairs to Rennies and the consistent sighting of snakes and rats at both beaches is an issue especially during summer.

"The grass has also taken up residency eating up the beach hungrily, Sussex Beach, in particular, has lost nearly all its sand due to excessive grass growth."

Council encourages people to report such problems.

"Shoalhaven City Council's maintenance crews are investigating reports of vegetation/weed overgrowth at Mollymook and Rennies Beach," a council spokesperson said.

"Council welcomes feedback from members of the public on maintenance of vegetation in natural areas. "The public is encouraged to contact council either by phone, email, correspondence or on council's website using the 'Report a Problem' form [www.shoalhaven.nsw.gov.au/Services/Report-a-Problem]".

Meanwhile, the concerned resident says the overgrown foreshore sends out a poor message.

"Mollymook is, without doubt, our most popular beach. It is beautiful, accessible and photogenic," he said.

"The south end is well maintained and looks amazing but it's the middle of the beach that's become really overgrown, most of the "new" bush are not natives either, they are weeds or been introduced by us, the fences that once bordered the bush have long ago been swallowed up, you can't even see the majority of them anymore."

He remembers a time when the foreshore was managed.

"I recall a few years ago there was a group who maintained our beaches, but we don't see them anymore," he said.

"Our coastline is one of the biggest drawcards to our area and to see them being so abandoned is a travesty, if preservation was kept up we wouldn't be in this current situation, like many who visit our beaches daily it's infuriating to watch it becoming dilapidated.

"It wouldn't take much effort or dollars, just a few days to cut it back, and clean it up."

He hopes more people will call council about the matter.
