Actually the 19th century abandoned town south of Cape York tip would be ideal. Alternatively Albany Island just off east coast of said townsite. Lots of empty water to east where things may drop into deep water. There was a brief flurry of suggestions a decade or two ago that a site there could be leased to a joint project with Russians but friends do not let friends/lackies mix with those sort of people. </sarcasm>
