You could try IDing it using wattle2 http://keys.lucidcentral.org/keys/v3/wattle2/ Otherwise, could you give me leaf length and width and number of flowers per flower head and I will give it a go.
The leaf in the 3rd photo was 110mm long including the leaf stem, and was 18mm wide at the widest part. That was one of the largest leaves of my sample branch. The maximum number of flower globes on the flower stems was 18 on several of the longest ones, the minimum number was 5. The tree was spindly looking and 5-6 m tall.
The comment in Wattle is that 'plants with pruinose (waxy) branchlets are scattered throughout the range'. That suggests to me that not having that character does not matter.
