GPSed. Spider burrow found under rock shown in first picture - in second picture, with a bit of image enhancement can see part of spider legs at the end of burrow (towards the top edge of the pic). The only wolf spider observed so far at this site, and and commonly encountered, is Tasmanicosa sp. (genus) so my ID reflects this. NB I carefully replaced the rock so as to not damage the burrow, spider and cockroach.
