Projections for Australian maps
According to the Australian Intergovernmental Committee on Surveying and Mapping (ICSM) here:

"The Lambert Conformal Conic is the preferred projection for regional maps in mid-latitudes. In Australia the national mapping agency prefers to use this projection using 18° and 36° South as the two Standard Parallels. Projection information: Lambert Conformal Conic; centred on 140° East and 25° South, and two Standard Parallels 18° and 36° South."

Cosgrove track
The Cosgrove volcano hotspot track is a theorized chain of volcanoes through eastern Australia.

I want to create an image like this. Coordinate data from Davies, Extended Data Table 1

Template:Location map+ places one or more location marks on a map, with optional labels. One of the examples is a map of Australia using Module:Location map/data/Australia with base map image.

OK. Looks OK for a start

Maps with overlays
Looking for examples of maps with overlays:
 * Kidepo Valley National Park has an svg overlay.
 * map is in a Template:Infobox protected area
 * location template is Module:Location map/data/Uganda
 * The base map is Commons:File:Uganda_location_map.svg
 * the overlay is Commons:File:Kidepo_in_Uganda_location_map_overlay.svg
 * Template:Superimpose may be what I want

Play with Uganda example

and with image_overlay added

Tasmantid Seamount Chain
Maps and tables for Tasmantid Seamount Chain.

Coordinates from GEBCO Undersea Feature Names.

Some info on Mellish Reef here.

Another base map is

Here are some location markers

First attempt at overlay is

Location map+ | Australia and New Zealand
How accurate are locations on Module:Location map/data/Australia and New Zealand using Template:Location map+ ? Very wrong!! Cape Howe and Point Danger are the locations where the state borders meet the coast. Errors are approximately 200 km.
