Without a photo showing how flowers/fruits are attached to their stalks, I would not be will ing to confirm this to species level. Amyema miquelii is the common mistletoe round Canberra, but pendula is also in the area. Michael B will know more definitely.
there was a fence so we could not get close enough to them they did not seem to be in flower. Michael B can probably get a lot closer to them as he can jump fences better. :)
