Lupis Arante, your latest photos are probably Acacia Disparrima.. note the shape of the pods. should have numerous longitudinal veins non anastomosing
And DreamTripper .. interesting maidenii if it is one.. I thought maidenii had more of an acute apex but my understanding is that its a highly variable species.. even just within NSW.
I also wouldn't rule out Acacia Melanoxyn as the ones up here are also differen't to those in victoria .. and again, its also highly variable within NSW. Certain strains of melanoxyn (eq in the new england area heading east) have smoother and lighter grey trunk bark, as well as narrower/more acute phyllodes .. which can lead to being mis-identified as maidenii... it doesn't always live up to its name "blackwood".
It just finished flowering where I live.. so one can tell the difference from the dead flowers still present on many.. but my observation is that some trees further south flower earlier than up here; so depending on which area of NSW you are in you may also be looking at a melanoxyn that finished flowering some time ago. Pods are coiled with melanoxyn too which makes it even more confusing.
