I'm pretty sure it's not Solanaceae. The opposite toothed leaves and opposite branches on the inflorescence aren't right for that. It could be in Scrophulariaceae. I noticed a fly on a flower. Is it the flowers that smell bad?

Last season's pods can usually be found under the trees. Even if they're in bad shape they can be useful, esp. if photographed next to a ruler. There are around 1200 types of Acacias and it's very hard to get a firm identification without pods, even when the photos of the other features are excellent.

Nice pics, but it's very useful to include photos of the pods too. But here are some possibilities: If you're between McKay & Canberra it might be Acacia leiocalyx subsp. leiocalyx. If you're north of Townsville it could be either Acacia mangium or Acacia polystachya. In A. mangium the secondary nerves (veins) are reticulate - i.e. they intersect a lot. In A. polystachya they tiny nerves are finely parallel and rarely intersect.

spot on - only nowadays it's called Ficinia nodosa

It looks like a Bromeliad. There are many kinds. Beautiful isn't it?

From the flowers, it's looks like a Hakea, or (less likely) a Grevillea. Definitely not an Acacia.

It doesn't look quite right for a Cyperus, though it is certainly in the Cyperaceae family. All the Cyperus species I have seen have flattened spikelets. The bracts and florets are arranged distichously, i.e. on opposite sides of the rachi (or axis) and offset from one another in a left-right-left-right pattern. In your plant the spikelets look to be cylindrical rather than flattened, i.e. the flowers are arranged all around the axis (360 degrees). Also in most Cyperus species the stem is triangular in cross section, whereas your plant appears to have a flattened stem. It could be Fimbristyis, Isolepis, Scirpus, Bolboschoenus or something else again.

Photo #3 looks like A. longifolia, but the last one (#6) isn't, as it has flat pods. It would be useful to see #3 in flower. If #3 is Acacia longifolia the flowers will be arranged in cylindrical spikes (~2 to 5cm long) sprouting out from the phyllode ('leaf') bases either singly or in pairs. The flowers should extend almost all the way down the spike to its base - i.e. there should not be a peduncle (stalk) at the base of the spike. These features do not definitely mean it is Acacia longifolia however, as there are over 1200 Acacias in Australia. To be sure you should collect pods, flowers and a sprig of a branch and compare them to those of a confirmed specimen at the Sydney reference herbarium.
