A bill to outlaw protesting within 150 meters of abortion clinics will be introduced into NSW parliament today.

The private member's bill, co-sponsored by Labor's Penny Sharpe and the National's Trevor Khan will also make it illegal to harass, photograph or cause distress to persons entering these premises.

If passed the bill will force Anti-Abortion protestors to abandon invasive tactics such as the use of signage featuring graphic images and the placement of activists by the entrances to abortion clinics.
