The Mountain Rocket (Bellendena montana) is just turning from its flower phase (above, and earlier, properly in flower) to its fruit phase (right). The fruit takes over from the flowers, and is very distinctive, flattened and hanging down, the resulting shape giving rise to the common name.
Actually I was taken by the appearance of the leaves on this plant, especially with the water droplets. I'm pretty sure it's the Mountain Pepper (Tasmannia lanceolata). The fruits, and I think the dried leaves as well, are now used as premium food seasonings. To quote from "Wildflowers of Tasmania" (King and Burns, 1986) "Tradition has it that the berries were used by early settlers as a substitute for pepper, and the practice still persists in feeding the leaves to unsuspecting strangers under the pretence that they are delicious." Who knows!
Now this one took me a while, but I think it's Lomatia polymorpha. I'm sure it's a Lomatia, but picking between the various pictures of L. polymorpha and L. tinctoria was a bit tricky. Apparently it's widespread on mountains and flowers in January. Check! The leaves also vary in shape to trick amateur botanists.
I think this last one is the Dwarf Leatherwood, Eucryphia milliganii. Interesting historical fact: "The name 'leatherwood' was originally given to Acradenia franklinii, possibly on account of the toughness of its wood, but by 1903 was being transferred to the Eucryphias, which produce honey". ((King & Burns, 1986)
