My reason for suggestion: fairly wide-spaced pinnae but would need to check glands for proper id.

This tree is only 50m or so from another very similar tree, which appears to more clearly be Acacia parramattensis (see related comments under that other sighting). There are many other trees like this in the same vicinity, but almost all of them have been dead for some time. The leaves on this tree don't look healthy, so it too may be in the process of dying.

Steve, if you walk there again would you mind to bring a branch perhaps of one of this specimen and one of a healthier tree in the vicinity? as you pointed out the specimen on the photo seems to be at the end of its lifespan and then it is difficult to id from a photo - at least for me. I googled pictures of A parramattensis, some with old foliage look similar, see for instance: https://davesgarden.com/guides/pf/showimage/456353/
I haven't noticed A. decurrens in this area before; there are however A decurrens in the pine plantation east and particularly southeast and it would be a worry if they spread.
Wattles have only a relatively short lifespan.

OK. I will bring you a branch to study in detail. Today I located half a dozen apparently healthy trees of this type, farther down the ridge at the location highlighted in the following location - https://photos.app.goo.gl/ADmRHA5SPU3MUBLs8 GPS data at the bottom of the photo. I see only mature and dead trees, but no smaller ones growing.

Hi MM
Steve brought material from a variety of Acacia of the area including from the plant of which he took this photo.
From this material I identified specimen that looked like straight A parramattensis and specimen like the one of which this photo was taken that had various degree of A decurrens as well ie I id-ed as A parramattensis x A decurrens hybrids; these are not listed in the Census of Vascular plants so I have intentions to investigate further, but not in the next months - the herbaceous weeds are overwhelming...
