              <p>Since the coastline tag is also supposed to represent
                the high water mark then I would say that they should be
                snapped together (since they then represent the same
                feature - that is, the high water mark). This would mean
                that the boundary data already in OSM 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.</p>

          <div>Exactly. So if anything we should be actively snapping
            them.</div>

    <p>Are there any links to these boundaries linked to the high water
      mark??? <br>

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

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