Hi,
The present coastline for the Hawkesbury goes from Box Head to Barrenjoey.
See https://www.openstreetmap.org/way/557825041
This is also use to define 'Broken Bay', both relations are correct in
OSM terms.
I have just corrected a shared segment for this way ... so my attention
was attracted to where it should be.
The PSMA boundaries run Box Head to West head then to Barrenjoey. I
think may be done so to have some legal thing applied to water craft
leaving Pittwater?
But a transport NSW document does state "Broken Bay entrance from
Barrenjoey Head to Box Head" which would suggest that the present
version is correct at least in a general sense if not precisely.

Note The coastline does not render in this area. The coastline carries
the name 'Mainland Australia'. There is probably a choice here - I think
OSM says something abut running from one headland to another, the issue
hear is there are 3 'headlands'.
