Sorry if anyone said this, but bring some sort of an accessory that gives you a valid reason for being in the area. Be it a dog collar and leash (looking for dog who ran away) or some sort of fishing gear or whatever. One friend liked to catch snakes/lizards would carry a book on reptiles. Get creative but it’s a good way to talk your way out of an encounter if you run into a hunter or hiker in the bush.
Also for water, you can siphon water and use a gravity fed timer to auto water with a drip system. They also make”crystals” that you can put at the bottom of the hole to hold more water and slowly release it incase you have a drought or can’t come by to water them.
I agree with everything else everyone said. Good luck
