> Could you please explain how NBN will pay for itself?

NBNCo gets a cut of the customer's payment to the ISPs for their Voice & Data Service.

> Not to mention, NBN Corp. will not be any different monopoly from Telstra Wholesale.

I believe NBNCo aren't allowed to sell services directly to the consumer.

> And regarding speeds, how is NBN going to solve that? Australia doesn't even have enough international throughput in the current network. NBN will make speeds even worst as the demand will only increase. The bottleneck here is not copper, it is international capacity. What's the point of replacing copper if the weakest link of the network remains.

There is plenty of competition in this area (http://en.wikipedia.org/wiki/Telecommunications_in_Australia...). Capacity has increased, reducing international traffic costs for local ISPs (and hence, the consumer).
