The Greens are proposing safe access zones outside of sexual health clinics in Western Australia to keep anti-abortion protesters away.
The policy involves 150-metre exclusion zones outside premises where abortions are provided, and makes it an offence for someone in the zone to "bother, beset, harass, intimidate, interfere with, impede, obstruct or threaten" anyone accessing or leaving clinics.
Greens candidate for the East-Metro region Sarah Nielsen-Harvey said it was concerning the One Nation candidate for Bateman, Michelle Meyers, regularly engaged in picketing with her pro-life church group.
Ms Meyers regularly posts photos of the group protesting on Facebook, and wrote that abortions were designed to "preserve the lifestyle of the mother".
She has been contacted for comment.
Ms Nielsen-Harvey said the main purpose was to ensure the privacy of patients, and to guarantee their safety, wellbeing and dignity.
"The practice of picketing clinics which provide abortion services is dangerous to people's physical and mental health," she told AAP.
Such laws are already enforced in Victoria, Tasmania and the ACT.
Marie Stopes clinic Midland centre manager Leigh Clifton welcomed exclusion zones, saying it had made a difference to her colleagues and patients in Victoria.
"They've said it's been such an improvement," she told AAP.
"(The protesters) are not able to approach patients, so it's much more comfortable for them," she told AAP.
Ms Clifton said the church group picketed outside the health centre every Friday morning, and for 40 straight days during lent every other year, alternating between the Midland and Fremantle clinics.
Marie Stopes clinic performed a variety of services, and some patients were targeted by protesters despite terminating pregnancies for genetic or health reasons, which was greatly distressing for them, Ms Clifton said.
