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 
... who knows? The possibilities are endless.

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 
exchange issues.

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.
