(Found) Nanotechnology has destroyed civilization and whales lure people to their deaths

[Leslie55]

Sometime around 1975-1985 I read a book about a traveler who was living in a world where nanobots that had been created and sent into the atmosphere to shield the planet from the sun had attacked the planet and destroyed civilization. A traveler in this world came upon houses where one whole wall was a screen of some sort, but too much time had passed since the destruction so he did not know what its purpose was. There are no books except in museums. People who are close to the ocean chain or tie them selves up at night so they will not be lured to their deaths by the siren call of people-eating whales. I believe at some point I became aware that the setting of this book was Australia.
