Photos are in Nearby Sightings and I couldn't copy the links until I had added the new sighting. Flowers are in Unidentified on 22 Sep 2018 and immature pod is in https://canberra.naturemapr.org/Community/Sightings/Details/3872156. The pods have now dried out (straight) and have released most of the seeds.
The suggestions were Acacia howittii and Acacia pravifolia. It is definitely not pravifolia, which has coiled hairy pods and hairy triangular phyllodes, it almost fits howiii, with straight hairless pods and resinous phyllodes. But howitii branchlets have hairy ribs. http://worldwidewattle.com/imagegallery/image.php?p=0&l=h&id=23681&o=1 With the information you now have, could you run it through the Wattle app again?
