In South Australia, as a requirement for building our house, we had to install water tanks. We have 22,000 litres of water stored, with pumps and filters. And we are on mains water too so it’s never used. We also have 6,000 litres of water stored for fire fighting. As do many other houses on our street and local area. Then there is the solar and storage batteries… We could go for a good while and we live in a metropolitan area! Rural Australians could probably survive for longer as isolation is their life anyway LOL ;-)
