The nbn from its conception was a half-baked, last minute idea made up by Kevin Rudd. If any public network was needed, it should have been wireless. The nbn discounted any possible future that resulted in wireless being a viable way of delivering the internet to everyone. Wireless is also necessary because things aren’t stationary. Cars can’t use fiber internet, for example. Fiber to every home is ridiculously expensive, with a large percentage of homes not even using any more bandwidth than is required to stream Netflix. Fiber also excludes rural areas, and any lower density areas in general.
A public wireless network would be utilised much more, as even a lower speed wireless network that is available everywhere and cheaper opens up more possibilities than a limited high speed network. It isn’t just speed that is important. We also have the issue of data caps. High speed connections that have 20gb per month data caps are pretty useless, yet a large percentage of the population can’t afford any more than that. The nbn, whether fiber or not, would always just result in a product a large percentage of normal people couldn’t even utilise.
The liberal party made the nbn worse, but it was a terrible idea to begin with. All the political parties are corrupt.
