Professor Reg Coutts, Director, ACS Telecommunications Board and an NBN Expert Panel member was more cautious when commenting on the impact no NBN.

"This is an NBN conference, not a Hypotheticals. We'll cope with the reality when the reality happens," he said. "The wave of broadband is global, it's not just up to what Australia is doing. [Cancelling the NBN] will just slow us down for a while."

As reported by Federal Opposition Treasurer, Joe Hockey, as a move to balance the budget.

During the month, Labor backbench senator, Kate Lundy, as "absolutely appalling" and "schizophrenic".

Despite his reticence to comment on the potential cancellation of the NBN, Coutts talked up the NBN to the CeBIT audience, pressing it to remember that the NBN project was just over 12 months into an eight to 10 year process.
