George,
I don't think this has been published anywhere; there is, however, a
list of under-served areas in an Excel spreadsheet published by the
Department ... Googling should provide the link.
What shows as "98% of the population" on a map depends on your data
sources, and on how you determine the cutoff.
I presume that the Department used Telstra exchanges as one data source,
since you can purchase these maps (from MapInfo; costs a bomb). For the
other half of the population equation, you would use ABS Census maps ...
I can't think where else you could get a sufficiently accurate measure
of where people live -- unless you used the electoral roll. But
geocoding ten million addresses would be slow and expensive!
So it's a matter of getting the source data, analysing distances, and
finally deciding what your cut-off criteria are. Then brace yourself for
lots of dissatisfaction - remember that 2% of the population is 400,000
people, perfectly enough to make lots of noise about being left out; and
inevitably, some people at the fringes will be left out, even though
their circumstances and remoteness are nearly identical to people who
are "in".
