maritime waterbody.
What do you mean by "maritime waterbody"?
A maritime waterbody are all those waters under the influence of the tides. You can
review article for natural=coastline. The coastline should be placed in the "high
water mean spring": https://wiki.openstreetmap.org/wiki/Tag:natural%3Dcoastline
If you're in Botany Bay or the other bays there such as

<https://www.openstreetmap.org/relation/1333569,> you're not at sea or
in the sea, or in the ocean.
Botany Bay is part of the ocean, not a separate inland waterbody. You can see
in the terrain the mark of the tides.
If you swim at a coastal beach you're swimming in the sea and the
ocean. At the beaches of Botany Bay, no one would say you're in the
sea or ocean. Nor would they say you're on the coast of Australia.
This is only a colloquial thing. That lacks of verifiability. For example, Dead
Sea is not a sea, really is a lake.
Botany Bay is unlike many conventional bays which are on the coastline
and part of the sea. You're right that these types of bays are part of
the sea and ocean, and other times they are part of a river, but
botany bay is really a river nor sea, if anything Botany Bay sounds
much more like an Esturary.https://en.wikipedia.org/wiki/Estuary
The rules for tagging are in the OSM wiki. Even in Wikipedia says Botany Bay is
an oceanic bay: https://en.wikipedia.org/wiki/Botany_Bay
The coastline is a natural feature. You don't mix it with political things. You
can use the tag boundary=maritime + maritime=base_line to delineate political
inner waters. Even the boundary runs in the mouth of Botany Bay, therefore is
respected local things that you mean.
Here there are instructions to tag an estuary:
