ALC (Christian Lobby) tries to oust Australian Sex Party

The nation's newest political party has come under fire from Christian groups even before its official launch.

The Australian Sex Party supports the exploitation and degradation of women through pornography and prostitution, the groups say.

The Australian Christian Lobby wants all other political parties to preference the party last on how-to-vote cards to prevent it taking seats in state and federal parliaments

"Pauline Hanson was rightly put last on how-to-vote cards because of her inappropriate views on race," lobby director Jim Wallace said.

"The Australian Sex Party should be treated in the same way for its inappropriate views about women."

The party launched itself at the national Sexpo event in Melbourne on Thursday. The party's platform includes opposition to the national internet filter, supporting gay marriage and adoption of a national sex education curriculum. Party convenor Fiona Patten says the party acknowledges the importance and scope of sexual issues in the lives of Australians.

"I doubt we can be all things to all people," she told ABC Television. Sexuality and gender were important issues not being dealt with properly, she said.
