User's notes
In roadside patch of of bush, on very steep slope, downhill of forest, but not occurring in the forest - only in area disturbed by vehicles.
Phyllodes: 22 mm long, 3-4 mm wide. Faint mid-vein present, not quite central. Tip is hooked. Gland on .margin. 7 to 9 flowers in a head. Pedicel pinkish, glabrous. Erect habit.
Close to A. lunata but discounted because out of range and main vein is closest to lower margin (not upper).

I considered kybeanensis but its description in PlantNet gave "branchlets as "sparsely to moderately hairy with appressed to spreading grey hairs" and "mid-vein prominent" these don't fit the above.

I mean it could be an escape like A. lunata or similar especially considering you had A. boormannii at the same spot which I'm not sure is naturally ocurring there. Not particularly sure though

@RogerF given your comments on the other sighting do you believe this one might be some sort of unusual hybrid?

I though I made a comment about this sigting a couple of hours ago it does not appear to have come up. The site in question is along the route of the gas pipeline. The GP authority planted seed of a variety of wattles along the wooded sections of the route despite being advised by me and others to allow natural regen from the adjacent bush to take its course. This included the very weedy bormanii, baileyana, pravissima and others. Who knows where they acquired the seed. Bormanni and pravissima readily hybridise because they are genetically related. Nearby Urila road, where the pipeline passes and I live, has the same weedy Acacias (including the purple baileyana cv) except here they are slashed every few years

Thanks Roger! Knowing this patch was planted after major ground disturbance clears up the inconsistency between the acacia reported on and the forest further upslope). I probably wouldn’t have reported it to CNM if I had realised there was a fair chance of it being planted, or of originating from plantings.

Actually Jane it is very important to report these type of sightings. Firstly if Roger is correct, it highlights a very poor practice by the gas pipeline company and the landscaper who advised them. Secondly given that this infestation does appear to be the result of shoddy corporate practice, it seems appropriate that the same company actually control the weeds they have created. @RogerF do you know who was the responsible company and do you have any proof (ie an email or other document of their intention) which we could use to chase up action on?

Its a long time since the gas pipeline went in. I'm not sure who the revegetation contractors were. We talked to the Pipeline authority at the time as they wanted feedback about the impact of the works. This is when our local landcare group told them not to plant anything but to allow natural regeneration to take its course but this was a concept they could not accept nor could a lot of landholders (mostly hobby farmers locally) along the course of the route whose ecological knowledge was zero. As I said earlier they now have a policy of zero shrubs above the pipeline and use a bush wacker to slash them very few years. Near where Jane reported the weedy Acacias there is a spot they missed with seeding and the adjacent A. genisitifolia shrubs have colonised the route of the pipeline.
We also have to be careful with our response as many property owners have planted different exotics (native and introduced) along their roadside frontages that include parts of the pipeline. The area of concern with the pipeline is where it borders nature reserves.
