Sorry!@! This was suppose to be in the Acaica ID thread. WHOOPS!
This was found on the far north coast NSW , very sandy soil, old quarry I think.
A. Floribunda?

A. Longifolia? I also found a longifolia patch the council have planted and found the leaves to have a very bitter astringent taste.
Found near a council depot 10 meter's back from a salt water creek, Far N N.S.W.

A. Maidenii? Dead flowers same location as the rest.

your top tree looks like it may be acacia longissima.. the second one not quite sure i don't think its longifoilia. possibly a type of melanoxyn

I thought so on the Longissima but that flowers Jan-may whereas Floribuda flowers now, as seen in the pic. Pale white flowers.
I was at a local nursery last week and they had a identical plant labelled "GOSSAMER WATTLE".
 
the flowers on that tree look a bit different to floribunda.. floribunda has much more loose and abundant flower rods compared to the quite sparse and tight flower rods in that photo.. theres only one other that i can think of which is a rarer one that should be left alone
 
The main 3 things to look for spotting acacias are:
1) Flowers (Inflorescence)
2) Leaves (Phyllodes - which are technically extensions of the bark, not true leaves)
3) Seed pods (Fruit)

Here's something I put together to help ID acacias (I'll add 'seed pod' section later)

This was one was found at a spot marked on the QLD Uni wattle key.
Was found in the EXACT spot found on the map that was marked as Acacia Floribunda. What you guys think?

It has some of the hall marks of A.Floribunda. The phyllodes look a bit sparsely distributed to the A.Floribunda I usually come across. The spikes 'usually' form in 3's at each gland in the types known to me. Can you take a photo of the base of the plant in a higher resolution photo?
