I think the top right hand leaves are Acacia baileyana, which has up to about 5 pairs of stems with leaflets plus an end one making up a whole leaf, and lower down possibly Acacia dealbata, which has about 11 pairs of stems with leaflets plus an end one making up a whole leaf.
There are many A baileyana x A dealbata hybrids on Mt Majura (and Mt Ainslie) showing a range of features of their parent plants; some look more like Silver wattle however with less pinnae and wider and fewer pinnulae, some look more like Cootamundra wattle but have more than 4 pairs of pinnae... I have tackled quite a lot of Cootamundras in that area including shrubs that were clearly hybrids; unfortunately Cootas and hybrids don't rely on fire to germinate...
