Limnodynastes dumerili
What I thought were white rocks in the dam turned out to be floating frog foam masses/egg masses, or rafts. On the day of my arrival there were two, but by the third day there were six. In the second photo, the eggs within the foam can be seen quite clearly. The Eastern Banjo Frog aka. Pobblebonk (Limnodynastes dumerili) is prolific now the breeding season has started, and I could hear at least half a dozen of them around this dam each night. They are a reasonably large frog, as were these foam masses - 12 cms or more in diameter, and apparently each raft can contain up to 4000 eggs.
Freshwater dam on rural property. Area surrounded by dry native woodlands. Foam masses found only at base of Salt Club-sedge (Bolboschoenus caldwellii) which grows in the dam.
I have also observed, or at least heard, the following species on this property in any one of its three dams: (1) Verreaux's Tree Frog (Litoria verreauxi ssp. verreauxi). (2) Striped Marsh Frog (Limnodynastes peroni). (3) Stoney Creek Frog (Litoria wilcoxii or poss. Litoria lesueuri). (4) Peron's Tree Frog (Litoria peronii). (5) Eastern Dwarf Tree Frog (Litoria fallax).
