SYDNEY, Dec 14 - Days after Hamas attacked Israel in 2023, killing some 1,200 people and sparking the war in Gaza, an inverted red triangle was spray-painted on the front of a Jewish bakery in Sydney, the first of a string of ‍antisemitic incidents ​in Australia.

Sixteen months and thousands of arson, firebombing, graffiti and hate-speech incidents later, ‍the head of the nation's main intelligence agency declared that antisemitism was his number one priority in terms of threat to life.
