A waterbody where plant and animal life matches or is close to that of
the sea rather to that of a river or lake.

In OSM we have no separate tagging for estuaries, this would not make
sense because it would just introduce yet another boundary problem
(where the river turns into the esturary and where the esturary turns
into the ocean). An esturary is the transit of a river into the ocean.
If you consider the Botany Bay to be part of the esturary of Georges
River you still have to decide where you place the coastline and if you
place it below the bay you have to tag the bay waterway=riverbank or
natural=water + water=river. Creating a separate waterbody that is not
part of the river but within the coastline is wrong in our current
Note in general the esturary of Georges River would be considered to
start much further upstream, likely somewhere around here:
at the transit from a meandering river to a ria
