What worries me about this ID is the larger, more mature frond. It looks closer to C. sieberi. No doubt there's a continuum between the two species, probably affected by environment. Not possible to be definitive without a full keying out.

David I don't have a clue and to be honest I have no idea the difference between C. sieberi and C. austrotenuifolia, but I was pretty sure it was one of the two. Will be guided by what you think is the closest match.

C. austrotenuifolia usually is found in more protected areas. It grows well in Pine Plantations. e.g., the western slopes of Mt Majura. The fronds are spreading and delicate, and very pretty. C. sieberi may or may not be a separate species, possibly a habitat variant. It tends to grow in exposed areas (e.g. the top of Mt Stromlo). Its pinnae don't flatten out and are usually short and somewhat "crinkled". But (as Max Gray told me many years ago), it's unclear if the two are separate species. I suspect a DNA analysis would tell the difference, if there is one. If pushed, I'd identify the specimen as C. austrotenuifolia.
