Tentative ID : *Arthropodium fimbriatum* – I don't have first hand experience baed knowledge of what this soft tussock foliage is (not a Poaceae, grass, spp.) .
Ciaran @Tapirlord do you first hand know this foliage please? (no fertile material seen in these months in 2010 that i visited and re-visited this site while I lived in Canberra). I suggest only tentatively: *Arthropodium fimbriatum* – I do not know with first hand knowledge if this really does identify to this species. Equally i consider this may identify to something else, perhaps an alien species (weed).
Could this foliage shown in these three photographs identify to *Arthropodium minus* more likely ? –After i have had time for some more searching of foliage information.
