More About the Normanville Communication Cable

Nocturnal observations around Glenelg marina and jetty

While this weekend’s scorching hot temperatures kept my wife and I out of the sun for the most part, we couldn’t resist making a late night beach walk down at Glenelg. While the habitats there are highly modified due to breakwater and marina construction, dune removal for coastal development plus stormwater, Patawalonga and treated wastewater inflows, there remains an abundance...
