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

Botany Bay is part of the ocean, not a separate inland waterbody. You can see in the terrain the mark of the tides.

This is only a colloquial thing. That lacks of verifiability. For example, Dead Sea is not a sea, really is a lake.

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: https://wiki.openstreetmap.org/wiki/Proposed_Features/Coastline-River_transit_placement
