ANTI-vaccine activists are using secret Facebook groups to set-up backyard daycare centres to skirt No Jab No Play laws.
Health authorities have expressed concern that such centres could become a serious health risk for the children involved with diseases like measles, mumps and whooping cough currently circulating in Australia.
Northern beaches mother Heidi Street this week posted on Vaccine Free Australia, a group with more than 5000 members, that she was taking "expressions of interest" for vaccine-free childcare.
"I would like to open a daycare in my home for 3-4 children, 2 days per week ... I have 2 children ... I have a strong passion for children's health and wellbeing and have a beautiful nurturing soul," she posted.
"Children's days would be spent among nature, a walk to the beach, learning through play and games. Please let me know if this interests you."
Ms Street received inquiries from supporters who suggested setting up similar home-based daycare in Ipswich, Cronulla, Adelaide and Sydney's western suburbs.
"Many families are concerned about vaccinating. Yes it's in response to No Jab No Play," Ms Street said.
The Sunday Telegraph revealed last week Prime Minister Malcolm Turnbull was urging all states to adopt NSW-style No Jab No Play legislation to ban unvaccinated children from childcare with a crackdown on the current exemption of conscientious objection.
