You're Jewish. You do realise what "Final Solution" is a reference to, no?
I don't think he meant it as a reference to Nazi Germany. And the actual content of his speech, i.e. an end to mass immigration and support for an immigration policy that takes into account cultural compatibility with Australia, was great and refreshing.
Too many people always look for a reason to be outraged with someone supporting ideas they oppose, find one thing (usually out of context or deliberately misunderstood), and use it to discard the entire argument and smear the person who said it.
