Casey was one of the areas I was talking about wanting to survey last
year but it was already done before the construction fences were even
taken down, street names and all (and a single GPS trace, now covered by
dozens more).

The Bing aerial imagery analyzer gives different results for different
areas, youre right, some of the newer parts of gungahlin are only 3
years old, but the imagery around Tuggeranong which I quickly checked is
showing as March 2001.

In related news, NearMap are flying Canberra as I write this, so expect
even more superior (and up-to-date) imagery online in the next couple of
weeks, hopefully with a little more coverage of unmapped areas to go and
explore.
