Aussie. You have been conned. "someone" will not know where you are flying in remote areas because because Airservices have not put enough ground stations in. 90% of remote areas will have no ground station coverage at the typical levels small planes operate. Can't even get ADSB coverage at 9000' between Merimbula and Moruya and that's hardly remote. Get a Spidertracks or similar if you want that kind of coverage.
