The Wiki articles are not a lot of help - Canberra has the Census figure from 2016 and ACT a figure from late 2017 (estimate?) which are something like 403 and 416.
I looked up the "villages" - the 3 biggest locales outside Canberra have a grand total of about 600 (Hall, Tharwa, Williamsdale)
I fair dinkum have probably gone the longest in my life ATM without visiting Sydney.
Last time was early 2007, with my old man & brothers to see those wankers from American Chopper do a show at the showground.
Last time I was anywhere near the area was a couple of weeks before Easter this year, stayed @ Kiama after coming down Illawarra Hwy for a few days.
