What happened to Australia First (I think - the very anti-immigrant party with the female leader) ?
Also, do evangelical Christian groups have any influence over any of the main parties?
One Nation was a joke - it only survived because the Conservatives in power at the time gave them oxygen enough to act as a distraction. That oxygen disappeared when they won a seat.
They were Primarily anti Asian, anti Middle Eastern, and anti African immigration. A lot of support came from 1st and 2nd generation European immigrants, who brought their racism with them.
The One Nation party "peaked at the 1998 election on 9 percent of the nationwide vote, electing one Senator in Queensland. The party has never approached these heights again, and while it nominally still exists it attracts a negligible percentage of the vote." (wiki)
The leader of the party was called Pauline Hanson - she was parodied mercilessly. A Drag Queen called Pauline Pantsdown had 2 top 10 hits with "I am a back door man" and "I dont like it". Backdoor man had a federal injunction raised against it as it was in the middle of an election and seen as prejudicial.
As for religion..... Most Australians are ambivalent, they will say I kind of believe in god but that's about as far as they go. We dont have much time for "God botherers" and we have less time for "god botherers" that bother us about god. The main churches have some power, but that is because it was established in the past.
Hillsong (evangelical) got popular for about 5 mins and has faded, there were some scandals - proving that any and every church run by human-beings is corrupt.
I may actually get to run the next installment of my Lords of Chaos game. Speaking of which, I'm running out of crazy scenarios for them to run into. Start shouting out ideas and I may pick one to add to the game.
Well, so far, they have killed Dora the Explorer, killed over 1000 bards at Bardopolooza, had a character that dressed up like a girl scout and delivered bombs and are trying to become sky pirates. In the next session , I'm having a cameo by Buffy the Vampire slayer killing some Vampires and Werewolves that are "inspired by Twilight".
