My thoughts on this identification for Austrelaps: Firstly there is still some uncertainty as to whether superbus even occurs in NSW (many records of superbus in NSW were made before ramsayi was described) . There are no records of superbus in NSW listed in reliable field guides (Swan, Sadlier and Shea 2022, Wilson and Swan 2021; however Cogger 2014 records it as occurring through southern Victoria to the extreme south-eastern corner of NSW). Secondly, based on the photo, we have to determine whether (for it to be A. ramsayi) the pale anterior edge of the upper labial scales is distinct and whether that pale colour covers more than one third of each labial scale in adults. Based only on that one character this individual has characteristics of both species (ramsayi and superbus) ie about half the labials have distinct pale colour greater than 1/3 of the scale. So I would recommend we leave this as ramsayi (noting also Csteele4' comments).
