Acacia found in Victoria, Australia. I think it's Acacia Longolfia. Someone on another forum says Simplicifolia.
The one with darker leaves is a different specimen to the other two.

A.sophorae I think. There is no simplicifolia in the wild in Australia.

Evening Nexians.

Any chance I may have found an Acacia Maidenii here?

Long yellow flowers (with more than one occurring at nodes), alternating, the curve away from the branch tip on every leaf, decent space between them, over 10m tall... They are just flowering here and no seed pods were located.

Thank you in advance.

I can confirm that it's not Simplicifolia

Hmmmm, I have no idea. But hello my fellow Aussie 👋 I'm a south Australian fella.
