An anti-vaccination group is reportedly encouraging parents to sign up to a fake church so they can bypass immunisation requirements for childcare.

Under a NSW government's 2013 law and the Victorian government's proposed law due to start next year, children who are not fully immunized cannot enroll in childcare.

But parents can get around these laws if they declare a conscientious objection on a Medicare form and have it signed by a GP, who first counsels them about the risks and benefits of immunisation, Fairfax Media reports.

One of the options for objecting is religion.

With some doctors refusing to sign the forms, the Australian Vaccination Skeptics Network Inc reportedly is now promoting the "Church of Conscious Living" as a religion that is opposed to vaccination.

"We have decided to create a 'religion', so, amongst other things, we can claim 'religious exemption', if the need ever arises, for ourselves and our children," the group said in a December 2007 newsletter, adding that it costs $25 to join.

The Church of Conscious Living is not registered as a church but rather a business with the Australian Securities and Investments Commission.

A spokeswoman for the federal government's department of health, which processes the Medicare forms, said it would "closely look" at the church but added that vaccination was not compulsory and parents could use any reason to refuse it.
