The safe lift point at the rear is under the spare wheel well.
Once you get your hand in far enough you will feel it.
It is not in the middle, but towards the front of the wheel well.
Of course, put a block of wood/rubber between the jack head and the lift point.
The safe place for stands at the rear is "inside" of the notches where the scissors jack would fit.
See the Round area that I have highlighted in the final image.
