HI Jacquie the system is increasingly glitchy. The coordinates are showing on my end - this is the one that took me three days to upload, the comments came up in an earlier listing but not the photos; here, the photos but not the comments. This is about ten paces up the path from the top of Corunna Lake, on an embankment at the edge of the lake; next to it in situ is the plant you've ID'd as that asparagus that is a weed; the best anyone would be able to get of the whole plant is the second image here as the plantings are densely clumped with other plants. The plant is behind the beach which is presently open to the sea.
RIghteo thanks Jacquie as always appreciate your deep insights, and the description of Bermi between the beach and lagoon is almost exactly..... will keep an eye out for further info, thanks again
