Eighteen species of waterbird have been recorded around the lake, including the salt tolerant Australian shelduck and the banded stilt, which were both numerous.
There was also a large number of silver gulls, thought to be a result of the proximity of the lake to a waste disposal site.
Species with much smaller populations include black swan, black-winged stilt, curlew sandpiper, eurasian coot, grey teal, hooded plover, pacific black duck, pink-eared duck, red-capped plover, hoary-headed grebe, white-faced heron, australasian shoveler and red-necked stint.

Six species of crustacean have been found in the lake, including Australocypris insularis, Diacypris compacta and Platycypris baueri.
Three species of insect have been recorded, including Necterosoma penicillatus and a species of Tanytarsus.

The endangered red-tailed phascogale has been recorded in the nature reserve.
