The Anglican priest whose provocative signs have become an internet sensation has torn strips off Pauline Hanson at a speech in Melbourne, accusing the One Nation leader of representing a "radicalised Christianity" that has no place in Australia.

Father Rod Bower, from the Gosford Anglican Church on the NSW central coast, has thousands of social followers thanks to his outspoken billboards chastising politicians over everything from asylum seekers to Australia's racial discrimination laws.

Recent messages include "Hell exists and it's on Nauru" and "Equality shouldn't cost $160 million". A picture of the anti-plebiscite message has been liked by more than 9000 people on Facebook, and shared more than 5700 times.

The signs have even sparked a Facebook 'appreciation society' with more than 4000 members from across Australia.
