I think this is a series of one individual but could be 2 individuals because initially they were a pair foraging together but one flew off while I was selecting the camera setting.
Various dietary targets observed in this minute or so: Seaberry Saltbush berries, nectar from Melaleuca lanceolata and (?) pollen from male Allocasuarina verticillata. (Possibly also ripe fruits of some Harlequin Mistletoe in the Melaleuca lanceolata??,or just the pollen?).
