This is a difficult one. The bee is certainly small, but the shape of the face is not like that of most euryglossines. I suspect that it is a small Lasioglossum, of which there are many, but there is insufficient resolution to pick up any firm clues.
I am fairly sure this ID is OK. Do you have a side on photo of a seed case? That is one of the diagnostics of species of Leptospermum. https://vicflora.rbg.vic.gov.au/flora/taxon/e67bc098-7731-4287-866e-ccc306e9bbb3#&gid=1&pid=1
