Assume Germany is defeated in 1941
1. The Jews of Germany and Austria have been crapped on severely since 1933, and there will be an impetus for many of them to leave. More emigres than OTL because no Holocaust
2. The Jews of Czechoslovakia and Poland have had 2-3 years of nastiness. They have seen most of their neighbors revert back to open and nasty antisemitism. A large number of them will want to emigrate (most of whom would have died OTL).
3. Those areas of the Baltic States that fell in to the German sphere after 1939 have seen quite nasty resurgence of antisemitism, again many Jews will decide to look for greener pastures
4. Hungary, Romania, and Italy have all to a greater extent or lesser extent have passed new antisemitic laws between 1930 and 1941. Many of the Jews in these countries will decide emigration is a good idea. With Germany falling in 1941 and no Fall of France Italy never declared war, and Hungary and Romania were only involved after Barbarossa so those laws probably remain in effect.
You now have large numbers of Jews (1-4) who want to move on - where? The western European countries will take a few (maybe) cherry picking scientists and other high value folks. The USA won't take any significant numbers, and will do its best to persuade Latin American countries not to take them (1). I doubt South Africa or Australia will want them, sure they are white but c'mon they are Jews. Like it or not if you want out of Europe the only place for these Jews to go will be Israel.
(1) The US immigration quotas in the 1940s did not apply to western hemisphere countries. The reason the USA/State Department opposed Jews going to Central/South America and the Dominican Republic was once they were there, and became citizens of those countries they could then move on to the USA unimpeded by quotas designed to restrict Jews. This is why even the 700 or so Jews on the SS St. Louis were the subject of State Department efforts, successful, to prevent their landing anywhere, even when they had already obtained visas.
