SYDNEY- Decked out in tight fitting red outfits and shouting, "No bad whores, just bad laws," Sydney sex workers protested outside NSW Parliament demanding an end to discrimination.

To mark International Whores Day the Scarlet Alliance called for the government to extend anti-discrimination laws to protect sex workers.

Alliance president Elena Jeffreys said NSW sex workers were discriminated against by banks and lenders when applying for loans, and by newspapers which charged inflated prices for sex workers' ads.

The boisterous group held with signs emblazoned with the words "Whore power" and one woman wearing a shirt bearing the word "Slut".
