Senator Siewert asked the Minister representing the Minister for Sustainability, Environment, Water, Population and Communities, upon notice, on 21 November 2011: (1) In regard to the King Sound boundary of the west Kimberley National Heritage listing, is the boundary: (a) to the shoreline; if so, how is the 'shoreline' defined; (b) to the high tide line; (c) to the low tide line; or (d) to the Australian Height Datum. (2) As the only listed National Heritage value for King Sound is the historical use of the galwa (Aboriginal raft), is the Minister aware: (a) that the King Sound area has the highest tides in Australia; if so, why is this not a listed heritage value; (b) of the published scientific paper by Semeniuk and Brocx that describes the: (i) international geo-heritage significance of King Sound, and (ii) the King Sound mangrove forests as globally unique; if so, why are they not listed heritage values; and (c) that the King Sound mangrove forests are recommended by the Australian Heritage Council to be registered on the National Estate; if so, why are they not listed as a heritage value.
