This video shows the view from Cottesloe in Perth Australia looking towards Rottnest Island.
The location is Princes St, Cottesloe. https://goo.gl/maps/hD2wJkWa2612
From the top near Avenmore Terrace and the bottom on the beach.
Both videos were taken within several minutes of each other.
The left frame shows the view from 2 meters elevation.
The right side is from 30 meters elevation.
You can clearly see how much of the Island is hidden by the Earth’s curvature at the lower elevation.
