At 97 years old, Jack Meister says it’s hard to recall all the details of his long life. But there’s one thing he’ll always remember ­– the concentration camp prisoner number tattooed on his arm at Auschwitz.

It was only when the camps were liberated at the end of World War II that the world learned the true extent of the Nazi regime’s horrors, its ideology becoming shorthand for evil and hated for generations. Now, 80 years on, neo-Nazis are bold enough to march in broad daylight on Australian streets.

Meister told 10 News+ it was “unbelievable” and “shocking” to hear about people calling themselves neo-Nazis.

“We went through this hell and still there’s still people still believing it.”
