Wireless and other technologies (that will no doubt improve over the
next 8 years) will fill in some of the rural gaps, satellite and
other less constrained by LOS technologies will cater for others,
Telstra might get off its butt and try to steal a march on the NBN

FTTH to your place (under the new NBN) would probably be the goer.
Any way you look at it, ADSL over copper has serious distance from

Mmmm ... Telstra might actually have to do something with all that
fibre. ''Use it or lose it' ... How sad.

True. But the last time Telstra 'pushed the envelope' as they say ...
network wise at least ... was back in the mid 1980's when they
finished laying the fibre to 'within 700 feet of most homes' in
Australia. They never did anything with that fibre. They never took
it to the next level. They never even looked like doing FTTH ...
which was the plan in the 80's ... that got dropped when bean
counters rather than engineers took over the network. It was supposed
to replace that copper we're still paying hideous amounts of line
rental on. But a captive market will still pay heaps of line rental
for existing copper .... until mobiles come in and there goes you
client lock in. So waiting on the market (when only one player was
seriously in the market) to work for us wasn't a winning strategy.
Telstra penny ante'd it's way out of hundreds of thousands of
customers and did little or nothing for the future of the network.

As I said ... FTTH looks like your best option, and with the new NBN
that looks like happening. (Under the old NBN we'd have had FTTN and
you'd have been left in the dust.)
The other alternative would be satellite, but that currently peaks at
about 400 KBs from memory which is a long way from what FTTH (or even
current urban solutions ... ADSL and cable) can do, and the providers
seem to charge like wounded bulls for it.
