Every religion with an ancient holy text can have an ethos for destruction...it's a matter of interpretation and most Muslims do not practice such things. In other words by political consensus Islam is not generally interpreted in a destructive manner by its followers.
I'd like to see some more facts about this tax business. It's not like the average Australian is going to be affected in any significant way.
Having studied constitutional law I would be shocked if it was unconstitutional in any way...and for legal purposes it's not technically a tax anyway.
