On Bruce Ridge, the species is most likely to be Stylidium graminifolium. To be sure it is not Stylidium armeria subsp. armeria, you should make a comment about the leaf width (armeria 3-15 mm wide, graminifolium 1-3 mm wide) and whether the midrib on the underside of the leaves is really obvious (graminifolium) or not obvious (armeria subsp.armeria). It is difficult to show these characteristics in a photo.
