In this Australia is vastly different from the US. According to our constitution we have a secular government, but for a very long time things didn't really work that way and religion dominated our society. We were a nation of white supremicist religious extremists.
That collapsed in the late 60s and through the 70s and the people turned away from religion and all the corruption that goes with it in a big way. In Australia any politician that dares mention the word God will find themselves losing the next election by a landslide, religion is not popular here by a long shot.
There have been a lot of religion based schools in Australia for the last couple of decades now but they're starting to find themselves in all sorts of trouble with our laws. I'm a big campaigner on that front too, if they want to receive public funding then they must accept students from all of the Australian public and they're not allowed to discriminate in any way.
That means they have to accept gay and trans students without discrimination, they also have to accept Islamic students and respect those student's religion.
A religious faction in our government tried to introduce what they called a "Religious Freedom" bill that basically stacked everything in favour of christianity. That bill never passed but we did latch on to the name and completely rewrote the entire thing in a form that did get passed. We now have religious freedom in Australia, and for many of us that means we have the right to be free from religion. People aren't allowed to come knocking on your door and trying to ram their religion down your throat any more, that's illegal because it's disrespectful to people of other religions.
It was only ever christians that did that anyway. No more young yanks in black suits calling themselves Elder.
