    Since the coastline tag is also supposed to represent the high

    from the government basemaps would just be their own mapping of
    the high water mark, and probably be less up to date or refined as
    our own.

Exactly. So if anything we should be actively snapping them.


Are there any links to these boundaries linked to the high water mark???


I would have though that CAPAD data would be accurate as it should come from the National Parks people using the gazette.


My trove searches only turned up low water mark stuff - but I only looked in NSW.
