The other problem is that tradies don’t know how to / can’t be bothered learning to reduce a buildings energy consumption.
We had an argument for weeks with the Site Supervisor because his subcontractor didn’t want to install the Reverse-Cycle condensers on the south side of the house because it was “too hard”.
One of the refrigerant lines insulation was nicked during installation and we started getting condensation stains through the walls.
The contractor came back and once again, he wanted to relocate the condenser on the north side. He kept blaming us for making him run the pipes to a location that was “too hard” for him.
This guy claimed to be an Air Conditioning specialist and couldn’t understand how a heat exchanger in direct sunlight will not be as efficient at cooling as a heat exchanger on the cold side of the house.
Consumer phones in regional areas are still an issue. As @baku said, 3G has better range than 4G (which has better range than 5G). If someone in the middle of the bush, or on a country road needs to use their 5G phone, they may not have coverage.
I have a friend that had to drive 10km with a cracked skull, ribs and broken arm and leg because he didn’t have coverage on his farm. He now has 3G coverage, but not 4G.
