One very old plant, recently died. I've found old dead plants elsewhere with youngsters popping up around it. No new plants growing beneath this one yet. Worth a follow up next year to see if new plants germinate here. 3 more plants nearby (12010).
Found dead in seasonal pool beside Maribyrnong River. ID not 100% guaranteed; back not as warty as usual but eyes also collapsed so may be due to dehydration/decay. Only other possible frog is Golden Bell Grass Frog, which is not found in Melbourne area.
