The problem is this bay, is not part of the sea or the ocean.
See https://snag.gy/h51wM0.jpg. The blue area is Botany Bay, the red
is the coastline, and the yellow is the sea and ocean.
The coastline shouldn't go on the inside of the bay, as it's not the
coast. Shoreline yes, but the coastline is only on the coast in red.
Outside Botany Bay you have the Tasman Sea.

What water body is Botany Bay https://en.wikipedia.org/wiki/Botany_Bay part of?
I don't think it's right too tag the inside of the bay as coastline.
"A coastline or a seashore is the area where land meets the sea or
ocean" the inside of the bay isn't the sea, hence the water/land
boundary isn't the coastline.
