> I've been involved directly in two separate decisions over the last 5 years where US companies decided not to invest in product and operations launches Australia specifically because of the cost of bandwidth to residential users

Cost of bandwidth and last mile network are completely unrelated. Australian bandwidth is the most expensive in the world because it is poorly peered mostly one-way expensive transit.

You could install gigabit to every home tomorrow and you'd still have 100GB download caps because an international link is $25/Mbps+

I find a lot of people confuse these issues, which is unfortunate because all of this NBN energy directed towards the price of Australian bandwidth could actually fix something tangible.
