<p class="MsoNormal">Except for the territorial boundary, Australia’s maritime boundaries in OpenStreetMap are incomplete. I have found two potential data sources for import from Geoscience Australia. Both are CC-BY-4.0 and I believe the waiver for GSA covers
these datasets, but I ask here to be 100% certain.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Link to the waiver:<o:p></o:p></p>

<p class="MsoNormal">Includes boundaries of the exclusive economic zone, contiguous zone and territorial sea (already in map):</p>

<p class="MsoNormal">Includes coastal water boundaries:</p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At present, state and territory admin borders in OSM (admin_level =4) extend out to Australia’s maritime territorial border (admin_level=2). It appears that the proper form would be to extend to coastal water limits instead.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any import would be fairly straight forward, just needs to be carefully integrated with the existing state/territory boundaries and the recently imported marine parks of Commonwealth waters (which are within the EEZ, but outside of coastal
waters).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Geoscience Australia has a useful list of maritime boundary definitions:</p>
