Shell implements found in archaeological sites in the Sydney region consist chiefly of fishhooks found around bays and estuaries such as the Cooks River. Other implements made from shell include scrapers and the shells hafted (attached using a binding) onto the end of spear-throwers. No spear points or barbs made of shell, as described in colonial accounts, have been found in archaeological sites.

Archaeological specimens of fish hooks are usually formed from the heavy turban shell (Turbo torquata). They have not been dated farther back than 900 years ago, reflecting the relatively recent introduction of shell fishhooks to Eora culture and their adoption by people in a restricted area of the NSW coast.

Archaeological specimens of shells hafted onto the ends of spear-throwers have shown evidence of resin used to haft them to a wooden throwing stick. (V.Attenbrow)
