Bungwall Fern

With a ready supply of oysters, poultry, dugong, fish, crab , kangaroo, turtle and more  the starchy mainstay of the Gubi Gubi peoples, on whose land resides Beachmere, was the Bungwall Fern.
With so much real estate about, and our sand dune habitat, there aren't many moist niches left for this fern to prosper in the Beachmere neighborhood.
But look to the base of the Malaleucas... and remember that these ferns were tucker for thousands of years.
The images are of one cluster of Bungwall that I've found in the Conservation Park on Bishop Rd.

It is a fishbone fern and it can grow to a meter tall and often forms large stands or colonies around the bases of paperbark trees and the edges of swamps. It can tolerate brackish water. ... The stands provide habitat for frogs, lizards and insects.The fern is very resistant to fire and well established specimens often have a mound of dirt at the base which indicates a well-developed root system. Because they are a fern they do not flower or have fruit, instead they develop spores on the backs of their leaves. Apart from their contribution to the aesthetics of the Melaleuca forest where they can provide a vivid green understory; they also stabilise the soil, trap nutrients and help to protect stands of Melaleuca from intense, high temperature bushfires.Redcliffe Environment Forum.
