Hi Ross, it could be glabrata or sericea. The former is taller and more branched, the latter just a compact little tussock. Their flowers are pretty much identical, so I can't tell from this photo. Both are present in the heath on Green Cape. I'd need to see the leaf bases - sericea has more obvious hairs along the leaf margin.
Thank you, Jackie. I'm afraid in my herbarium back in Botany Year 2 Uni days only scored 85% on IDs. I seem to have slipped much further back these days. I usually snap photos as I walk but will have to stop and try for more detail in future. :)
