Well it's nice to see the racial discrimination laws put in their proper historical context, at least Mr Wertheim doesn't deny Zionist terrorism or try to suggest that the diaspora wasn't raising funds for violent and at the time illegal action in Palestine.
It's refreshing to see a clear statement of the genesis and intent of these regulations, the HR and vilification regime was enacted specifically for the purpose of insulating Jewish people against criticism and the Jewish community against scrutiny or oversight.

Actually I should clarify that post because I was interrupted and had to leave the room, let me suggest that Jewish activists and their supporters are the proprietors of the HR and Anti discrimination regime and that Jewish groups like the ADC of B'nai Brith and others function as "committees of public vigilance", collecting information on other Australians for their own use and to be passed to law enforcement if they see fit. To look at it another way Jewish groups and individuals are also accused of rent seeking and profiteering from HR regimes, both here and overseas, if that's offensive or makes people uncomfortable then let's discuss and get into specifics.

There's way more racism among the non-white, non-europeans.

Individual do you mean "Racism" or just ethnocentrism? Ethnocentrism is a good thing and beneficial to a multi racial society. "Racism" on the other hand is a concept invented by Jewish activist Leon Trotsky (Lev Davidovich Bronshtein) to identify classes of people in Russian society for his description of "Peculiarities of Russian development".
Since Australia has no peasantry, no state religion and no absolute monarchy the word "Racist" has no context in our society.
I assume you're coming from the third position, the more realistic perception of race relations, so:
"Racism" in Australia today is a byword for boorishness and a lack of what the wealthy inner urban classes would term "sophistication", "Racism" is identified with the provincial or outer suburban poor, which paradoxically enough today includes most non European colonists.
"Racism" in 2013 therefore is in itself a class distinction, poor and backward people are "Racist", rich people who live in the city are "Anti Racist".
Non European colonists are commonly seen as "racist" by other poor people who think that they are a little bit better than their neighbours in the outer suburbs and provinces.
You can understand also why the rich, inner suburban Jewish population stands out in this area, especially after the way they pummeled some fairly feckless and quite sad individuals for "AntiSemitism". Loudmouth fool and homeless crank Brendan O'Connell is still in jail for upsetting two young Jewish men who would have probably been applauded by all if they'd just given him a smack in the mouth and walked off instead of crushing him like a bug and having him jailed.

"As there was no law against group libel he had no alternative but to find against her"

Then indeed why isn't there a law against group libel?
Why a special case for racial groups as opposed to other aggregates of people?

This smells of politics - not of justice!

"Making Aliyah" is a term for snatching somebody's home territory as self-styled Übermenschen "born to rule".
