As to what coochiee was saying, I'd heard about Australian Croatian fascists meeting sticky ends, but I hadn't heard that was Jewish vigilantes, I heard it was Yugoslav spooks. I suppose it could have been both.
This article says the watch shop was in East Melbourne, I thought I remembered it was Richmond.
But yeah the guy was a Jewish partisan in Lithuania during the war, so he obviously had some useful experience in killing Nazis, that he may well then have utilised in Australia's leafy burbs. I would like to think he did.

"It wasn't like Nazis came here without the Government knowing. Like, from the outset, you know, Holocaust survivors were literally on boats leaving Europe ... and there would be Nazis on the boats. Nazis who would taunt them... They would go into migrant hostels to restablish or start their new lives as Australians, there would be Nazis there that would be openly vilify and taunt them and persecute them as Jews."
Some Holocaust survivors report coming face-to-face with their loved ones' killers, who were living freely in Australia.
