Frank Yardley from the NCCARF Emergency Management Network at RMIT
University pointed out a Senate Inquiry into preparedness for extreme
weather events. It invites submissions on the preparedness of major
infrastructure, including telecommunications:

My suggestion would be that as a matter of policy, the combination of
the NBN and mobile phone networks should be made as reliable as the old
PSTN was. This should not be just for voice calls but for data as well.
The Public Switched Telephone Network (PSTN) used underground cables and
switching centers with backup power supplies. The system would therefore
work during power failures, floods, cyclones, fires and other disasters.
The NBN relies on mains power in the customer's premises to function.
While there is provision for battery backup where a voice service is
provided, many people will be using VoIP via the Internet, where no
battery backup is provided. Also the fiber optic cable may be more
vulnerable to damage, where it enters the customer's premises. Mobile
mobile phone towers may be more vulnerable to damage in disasters.
