Megan we have not observed Gang gang activity at this hollow previously - would you be willing to monitor this tree by visiting twice in November and then again in December? teh survey guidelines are at https://canberra.naturemapr.org/Community/Species/Sightings/15084
Hi Michael, Sorry I missed this message. Happy to go back again this month and see what's happening. I'll be there on this Friday. It's a trek for me, but I have to visit Yarralumla that day, Megan
