That's a good spot...but no it's a stump.
There's two...one not far off the fence line which is stretching forward to crop grass and a smaller one facing away from the camera to the left and slightly lower (within the blue marked area.)
I didn't shoot at them in these positions, just over 340m, but they made their way a little lower off the crest about the middle of that area below where the second, smaller, one is in the image. That brough them to slightly under 300m. They were not big ones, maybe about a third smaller than the one that took a nap right next to me rifle. I didn't think people would find them as neither actually looks like a kangaroo standing up, because they're not standing up. with a side profile.
Tks for pointing out, barely recognizable with the direction and still mainly just a blur. Where's that ultra high-res? lol.. Envious of the area and love seeing the pics.
