The wreck site of the Mary Cumming has not been positively located nor identified, so an assessment of its archaeological significance cannot be made. It has historical significance for its association with its owner Henry C. Pigott, an inaugural Melbourne Harbour Trust Commissioner and shipowner. The Mary Cumming is representative of a type ie: it was a typical British built, coastal trading vessel, however the predicted state of preservation of the site is poor given its location on a rocky, cliffed coastline in a high energy environment.
