The party, which is set to be introduced at the Melbourne Sexpo, will seek offices in state and federal parliaments on a platform opposing the government's proposed Internet filter, demanding a national sex education curriculum and supporting same-sex marriage, The (Sydney) Daily Telegraph reported Monday.

The party's slogan: "We are serious about sex."

Fiona Patten, founder of the Australian Sex Party, said the proposed Internet filter is "a real step backwards to where we've come. In fact it's far more censorial then we probably were 30 years ago."

She said the filter would put Australia's Internet sex industry out of business within five years of implementation.

"Material that would be classified X-rated ... is considered illegal content and that is material that is currently available ... in newsagents," Patten said.
