Facebook suggests mm-wave spectrum should be free in Australia

Not sure how this will 'help' the NBN since the last-mile is not where the massive congestion is anyway.

(Well unless you bought into the "Wireless-Broadband speed = Wired-Broadband speed because the both contain the word 'Broadband" misconception' and are struggling with sharing the limited airwaves with the other thousands of schmucks (not to mention the many thousands more who have a legit need for wireless comms), and I doubt this will help there either since it is just the same limited-resource-distribution problem in a different frequency band!)
