I'm confused. First, you're over 4.25 kilometers out to sea when your Mavic tells you that it only has enough battery to RTH. You ignore that warning and continue in the opposite direction (further away from you) another +1,500 feet (meaning an additional kilometer round-trip), when you finally decide to turn around. By the grace of the drone gods, you make it back to your position on the beach with roughly 14% battery left (at a height of 65 feet). Instead of immediately landing, you say you were spooked by 2 big "eagles" (on the beach? White-bellied Sea-Eagles?) and instead of going straight up (or down), you decide to continue away from you inland. You fly another 1,800 feet in distance (again, meaning more than +1 km round trip) and climb an additional 135 ft in altitude until your battery reaches 10% and enters forced critical battery landing. Do I have something wrong?
Either way, you're going to have to go find it. It's deep in the bush and potentially up in a tree. Here's your location from Google Earth. It's likely immediately under the last point where you had a signal, as it was in landing mode (it would have stopped coming back in your direction after the signal was lost and landed straight down). You'll need to hack through the bush and bring a GPS device (phone, etc.), hoping you'll get a signal under the canopy. Here are the GPS coordinates ( 29°17'40.83"S, 153°20'22.10"E). Good luck mate.
