Been away for a week but have a couple of comments to add.
I think tail colour is an easy and reliable way to separate a grey female
Wallaroo from an Eastern Grey, at least in our local area - the tail is
consistently cream or even pale yellowish, as shown in Con's photo, Eastern
Grey invariably has a black end of the tail. Very useful when the animal is
fleeing from you. I note Philip's comment about Red Kangaroos having a pale
tail but would be surprised if there are any wild ones within 200km of the ACT.
As regards distribution, there are quite a few Wallaroos in the quieter,
hillier parts of Goorooyarroo NR, I have seen up to a dozen at a time there.
Last year I saw 2 near the Mt Ainslie summit, the only Wallaroos I have
recorded there. They may be part of a small resident population, or perhaps
more likely, wandered across the Federal Highway from Gooroo. A few years ago
while doing bird surveys along the undeveloped parts of the Molonglo, west of
Coppin's Crossing, I saw many Wallaroos (and a lot of feral goats!).

Subject: Pale-tailed Kangaroo on Black Mountain Nature Reserve, a Rose Robin
and some migrating honeyeaters
Not a bird, but someone conversant with macropodic marsupials might know why
this one has a pale tail.
There was a female Rose Robin lurking between the electricity substation, the
CSIRO workshop and the ANGB plastic house, Frith Road this afternoon. I heard
Rose Robin calls on three other occasions but was not sure whether it was the
same bird. It was hanging around with a large MFF. There were large parties of
honeyeaters (up to 50). Going on the calls alone, White-naped Honeyeaters were
in the majority.
