Not reporting an actual attack, this time.
This is more the Community Service Announcement.
Maggie in question lives in the large gum on Studley Park, nearest Esdale Street, and has done some for at least the last 5 years. He is well known to the locals.
The trigger or offending item is bicycle helmets. Remove the bicycle helmet, in the park, or as you ride by, and he STOPS swooping.
