This is a street scene from the sea side village of Kamari on Santorini. An Australian just glimpsing the photo might think it an Australian scene.
I asked people and then did a web search trying to find out just who was responsible for introducing them to the Greek Islands.
I didn't find this, but I did find out from Wikipedia that Eucalyptus trees have spread widely round the world where they have proved both a blessing and a curse. A blessing because they are a hardy tree with many uses, a curse because they have affected the local environment.
