They are not typical C. australis pinnae. I wonder what they are?

How so David? Hypolepis or perhaps Calochlaena are possibilities at this site as well.

No, it looks like a young Cyathea, but the pinnae are "pointier" (I don't know the correct botanical term... acuminate?) than normal C. australis pinnae. It would be helpful to look at the trunk (if it exists).

I take that back. While some of the pinnules are more serrated than others, I think it's within the normal range of variation for C. aust. I took a careful look at the C. australis that planted itself in my garden (Merimbula) and it's not sufficiently different to be a concern. The Bendora Road area is certainly a fern hotspot. I came across a couple of examples of Asplenium trichomanes there many years ago.
