When I commented on this earlier I had not checked the BA
atlas-plus website. From this, I find that the ACT sightings, when
reported, will be the easternmost in ACT/NSW (Steve’s taking the title
here, narrowly), replacing ones from the Weddin Mountains (which I take to be
from Richard Allen’s meeting with them a few years ago) and Coonamble.
As to Australia-wide, they are further east than one at Lake Nuga Nuga, Q,
which unlike Canberra is technically east of the GDR. However, they
will fall far short of the one at Caloundra, right there among all the
Victorians on the Sunshine Coast.
