Ok I'm having issues understanding the switch to NBN.
we are forced to move to the NBN due to the government but we are always forced to change our plans??
cant I just keep my existing plan and just be migrated to the NBN?!
Yes, you will be forced to change plans as their cost to provide the service is totally different to non NBN plans.
While Optus says you might be able to keep your existing plan (I remember seeing that in some of the communications I received), I've never heard of anyone actually being able to do so.
