Here is the Liberal Party of Australia’s NBN policy (link). The policy promises that the NBN will be built more cheaply and more quickly, but the down-side is that it is also an inferior solution. The main contention is that the Conservatives will not offer fiber to the premises and will keep the existing copper network. Fiber to the premises will only be offered in new housing developments and copper to the premises will be kept when it already exists. The problem here is that if your house is a long way from an exchange, then the NBN Internet connection will be slower (as is the case today).
