I bemoan the loss of conventional landlines. We have gone backwards in a huge way and lives have been lost due to the dumb reliance on unproven technologies.
Here's my firsthand experience from last week (in case you wondered where I'd been)
We had been without power, water, mobile phone and internet for 6 days from 10:00pm Christmas night (25th) here due to a massive storm (classified as a tornado actually) which took out over 144,000 people's electricity across a huge swathe of south east Queensland. We had 150km/hr winds and horizontal rain. We had our bags packed at the front door waiting for the roof to be torn off as giant gum trees around us snapped off and were uprooted.
What happens in a situation like that is the following:
- The power distribution system is massively damaged- power poles, crossbars and HV sections destroyed. It's pitch dark until you get your torches up and running. All the 33kV lines and LV lines around us had such significant damage, several of our main roads were impassable. I went out at 10:30pm and helped cut up a large gum tree blocking our main road in and out so vehicles could access.
- Mobile phone reception is the first to go after power, as the thousands of lightning strikes kill the towers which are placed on high points. The ones that do survive, last maybe another few hours before their backup battery banks rapidly fail- they now have no grid power to operate. All three major carrier networks go down in our area and many other areas. There is no communication at all. Not even SOS (emergency) calls work. Your phone is completely dead, unless you drive about 15km to an area with power and cell connection- if you can get out due to fallen trees and power poles/cables. Roads are blocked everywhere.
- Local TV and terrestrial radio goes off the air as the transmitters are damaged by the storm and then with complete loss of power.
- Internet is via fixed wireless in my case and the repeaters were struck by lightning and out for several days. I was able to get mine up and running a few days into the outage, by running the roof mounted dish and router from my generator and being able to make calls over Telstra WiFi calls (iphone).
- Others on the NBN (national broadband network) have no internet for over a week as the fibre nodes need power to distribute via the old copper lines to the subscribers.
- The water lasts for a few days until the local reserviors run dry. Our water is gravity fed from very large reserviors, where the water is pumped (by electricity) from one elevated part to another. The entire city experiences water pressure or loss issues due to the pumping stations being damaged/offline (650,000 people). Ironic, as all the local dams are now overflowing due to a unprecedented flooding event where we got 550mm in 12 hours one night. Lucky we are 150M above sea level. We filled all our water dishes, saucepans and even the bath before the water stopped. As the bath was above the house (2nd floor), I could have a shower by siphoning the water to a shower rose under the house via the garden hose out the window. LOL.
- Electricity crews are working everywhere, 24 hours a day, but have to stop when more storms and flooding rain prevents safe work.
- My generator (luck I had one) ran the fridge, fans, lights and even the bedroom air conditioner for 5 days, 12-14 hours per day for a week. Lots of trips to the petrol station (about 1litre per hour- 2.5kVA generator).
- Old people had no idea what was going on.
Nobody had phone, nobody had internet (except one or two people out in the valley who did like I did and ran their starlink from the generator). The community centre were people could go charge their phones, make a call perhaps, have a shower and get some free food got flooded, closed and access was impossible due to flooded roads.
Constrast this with copper POTS. Power was supplied from numerous exchanges, all with backup generation. Phones are passive devices- need no power of their own. Entire areas never went totally down- there was always emergency calls and redundancy. Where power lines went down, the phone lines often survived, we easy to repair, or mostly ran underground in the first place. Sometime water could cause trouble, but it was localised and not widespread.
Mt tamborine was very badly hit. Our valley (Bonogin) was also hit hard.

The "tornado" that hit on Christmas Day was the biggest disaster the region has ever faced, according to Scenic Rim mayor Greg Christensen.
