There is often a dense mat of fennel pondweed, stoneworts, and ditch grasses in the water of the lake. Surrounding the open water is an almost continuous belt of the introduced bulrush "Typha orientalis", behind which various sedges, rushes and reeds grow. Beyond these is a belt of trees, mainly paperbarks and swamp banksia backed by orange wattle and flooded gum. The higher sandy ground on the eastern side supports open woodland dominated by candlestick banksia. Some 351 vascular plants from 77 families have been recorded from the nature reserve, of which 99 are introduced weeds. Twenty six species of algae have also been recorded.
