Open Street Maps (the data base OSM) only documents the high water mark... because that is easiest to determine from the tidal (or seasonal) wash up. Determining the low water mark from satellite imagery leads to disputes of where it is... Generally OSM tries to get away from disputes.
As Nic said, the relevant data (for Tasmania) is on ListMap. No controversy necessary.
