The diaspora is in irreversible decline due to assimilation and intermarriage rates. As the number of Jews drops, we will start to see Jewish schools, synagogues, kosher bucheries, and other institutions close down. Then, the last few religious Jews, who will find Jewish life now impossible, will go to Israel. It will probably all happen by the 2040s.

The country's drained empty of professionals and whites as the third world has taken over in NZ, all that's left is the older folks (who function as slum lords to the overtaking Asians). There are few jobs in NZ but plenty in Australia.

You are wrong on the demographics - the overall Jewish population in the diaspora will decline for a few years more, then will reverse as a growing Orthodox/Haredi population becomes big enough that their high birth rates more than compensate for the negative population growth of secular Jews. It is happening in the UK already.
