I wasn't suggesting other wise, just pointing out the majority of the
roads in sparsely populated area may not be surveyed by someone any
time soon  (if at all).

I wasn't adding new rivers, I was tidying up existing ones, although
the stream data may be better again but I'm yet to see it so no idea.

No one is actively encouraging it, although I am trying to locate some
more grey nomads that do tend to end up on a lot of back roads,
especially as they head north for winter and then journey south at
about this time of the year.

The property boundary data set is exactly that, property boundaries,
it just happens that the gaps between property boundaries has useful
other information if you can figure it out.

There is a number of rivers that partly exist due to existing ABS data
imported, these boundaries line up with natural features at times,
other data sets that just became available add to this body of
information already import into the system.

There is bearly enough active people in Australia to make up the
numbers needed to form a LC, I highly doubt we'd get enough local
people across all of Australia that even a small fraction of data
would be imported this way. I just don't see this as practical unless
we get a large number of Germans helping us out :)

hmmm perhaps I wasn't clear, you do realise there is 2.1 million
property boundaries right?

There is only a very limited subset of geospatial data that has been
released, about 31 sets of geographical data so making backup copies
now will prevent them from disappearing entirely, although that
doesn't mean improved data sets will be released.

Exactly... and the xls files and all the other non-shp files...
