..Growpen, if you're on the east coast, i'd say your acacia is a variety of A. mucronata..
wira, regrading A. melanoxylon vs cyclops, my eyes i think were weary, and i haven't seen a lot of victorian varieties of melanoxylon of which the pods do look like the posted photo, but in new south wales the pods are significantly more twisted, and the aril pale pink (not red) ..it really should be split into two varieties..depending on flowers you may be right..i do not know if this variety of A. melanoxylon has been chemically tested..it is the quite different NSW form that was found to have only very small amounts of DMT..
also wanted to also mention there have been one or two underground reports of finding DMT in Acacia baileyana (native Cootamundra, southern NSW, Australia and grown in Europe) but i don't know the percentages or details..
..as A. cyclops is of particular interest to the nexus (thanks again Primal Wisdom) here's some more images to assist ID..a reminder it is naturalized in many parts of Africa and also the Canary Islands..
