A complete guess. The flower has something wrong with it and has not opened properly. I am assuming the out of focus three lobed leaves belong to it. It could as easily be Hypericum gramineum. I am inclined to mark it Inconclusive Evidence.
Taking the photo of the plant was an afterthought after photographing the insect so I did not get photos of the leaves etc. The other photo which probably does not help is here: http://canberranaturemap.org/Community/Sightings/Details/3367385
