If available flowers in this season time of year and your time's available, photographs of open flowers will help identify and then confirm this sighting to species .
@jonvanbeest and @Tapirlord Please check out the _Seringia_ spp. as well ? I am looking again especially at these fruits shown as not matching fruits enclosed in bristles, yet otherwise similar, in foliage and pre-flowering inflorescences, to _Commersonia_ spp. and _Androcalva_ spp. .
I reported this as Hardenbergia violacea but there has been an undocumented change to unverified climber. This means I can’t verify it until I once again say it is hardenbergia.
I can see the glands on the rib between the pinnules in the leaf in side view. Difficult to tell apart from A. mearnsii. Look at the first pic at Acacia mearnsii showing the dark colour of the branchlets for A. mearnsii. A. parramattensis does not have that colour, I think.
