Below is a free map using Google My Maps and Chat GPT. From start to finish it took under 4 hours, which I think is quite good. The first hour was spent crafting the prompt to create the CSV (comma separated vector) file that you can then upload to your map, saving you many many hours of work. I am not sure exactly how many markers this map has, but it is in the hundreds with Airport locations in Australia as well as 4x4 tracks, wineries, playgrounds, ski spots, mountain bike tracks, camp grounds and surf spots.
