I don't know if any of these are possible but giving it a try (not even sure if they're native plants of course).
First two from Hogwash Bend a nature reserve on the banks of the Murray River.
The last ones are from further south in the Adelaide Hills; the first of them is a wide angle view with my feet in it, followed by a more closely cropped section. They were growing on a sandy track through brushland. At first I thought they were 'lichen-type' growths, but now I'm not so sure.
