There are few freshwater lakes associated with coastal dunes in southern New
South Wales (NSW). Lake Nargal near Narooma, Bondi Lake near Bega, and a small
lagoon near Pambula have little in common limnologically with coastal dune
lakes of northern NSW and southern Queensland. They differ in mode of origin,
are less dominated by NaCl, are less acidic, are more speciose, have few
characteristic dune-lake indicator species, and moreover contain certain
southern species. However, a re-examination of data for Lakes Windermere and
McKenzie further north at Jervis Bay suggest that these are classic
dune-contact lakes rather similar to those in northern NSW. Differences and
similarities are largely influenced by the extent and therefore the
hydrological influence of the contextural coastal sand mass and by
biogeography.
