In 2019, the Deep History of Sea Country (DHSC) Project team found and published two submerged archaeological sites in Murujuga (Dampier Archipelago) Western Australia . Following publication in 2020, a further discussion has ensued and was published in the journal Geoarchaeology by Ward et al , with a subsequent response to their critique published by Benjamin et al . This coincided with the project team returning to Murujuga in 2022 to collect further field data and to confirm the nature and context of the two underwater archaeological sites located in the shallow coastal waters of the continental shelf ( in press). This notice seeks to update the PLOS ONE readership on the supplemental data underlying  now made available and open access; to provide additional methodological information; to address errors in the statistical analyses for Figs 7, 8 and 12; and to provide additional discussion of interpretations.
