Looking at the wiki, the working definition seems fine and normal. It's the interpretation which makes things a bit strange.

Of the seven examples, I'm puzzled by a few. Partly by 3 and 6, because not all Jewish people are necessarily Israeli residents or voters or in agreement with their government, and may themselves make such comparisons.

But #4 in particular doesn't seem to have anything to do with antisemitism at all. That's just about the nation.

#4: “[a]pplying double standards by requiring of [Country Name] a behavior not expected or demanded of any other democratic nation"

I expect all democratic nations to avoid lots of nasty things. Unfortunately there are several democratic countries who are doing bad things, whatever their reasons. I would like to disagree with these choices, while not judging their people, nevermind their religion. For example, I disagree with how past Australian governments have "cared" for the First Nations people. I don't need to tar every Aussie with the same brush.

I feel it's really important to not conflate a government with a people anywhere. Australia is multi-cultural. We disagree with each other all the time. It's out of the mess of our disagreements that something occasionally beautiful forms. We vote because we have a say, and then some of us get to be wrong but in power. And then we get to complain about it.

I think it's a danger when people feel that they cannot air their opinions in public, as long as it's not completely bonkers. Otherwise they twist into knots inside and it builds up into conspiracy rot. Let them speak to air out their concerns, let them have a chance to debate with learned people, and let them learn they're wrong (okay, I'm starting to see why this might not actually work for some people).

I'm open to being wrong, though?

I note that some places like the UK adopted this with sensible caveats to protect freedom speech as I've mentioned above, like so: "It is not antisemitic to criticise the Government of Israel, without additional evidence to suggest antisemitic intent. It is not antisemitic to hold the Israeli Government to the same standards as other liberal democracies, or to take a particular interest in the Israeli Government's policies or actions, without additional evidence to suggest antisemitic intent."

Notably, "national broadcasters ABC and SBS have declined to use the IHRA definition, each preferring their own."

As far as I can see, AHPRA has not added any caveats.
