Mangroves

"There are only a few Grey Mangroves (Avicennia marina) in Lake Illawarra. The lack of change in water levels between tides being the major contributing factor. The shorelines near the channel entrance are the only are where mangroves exist." [1]

Saltmarsh

"Small areas of saltmarsh occur at various points around the lake. They generally occur around deltas of creeks entering the lake. Plant species present include glasswort (Sarcocornia quinqueflora), saltwater couch (Sporobolus virginicus), sea rush (Juncus kraussii) and sedge (Cyperus laevigatus)." [1]
