A group that believes vaccines cause autism and cancer should have its charity licence removed because of irregularities in its financial statements and its lack of charity work, critics say.

The Office of Liquor Gaming and Racing has confirmed it is investigating ''problems'' in the Australian Vaccination-Skeptics Network's financial statements.

The anti-vaccine group has raised nearly $2 million in the past seven years but has never done any ''charity'', according to Stop the AVN, a coalition of critics formed after the parents of a baby who died of whooping cough were targeted by the network.

Stop the AVN spokesman Ken McLeod said he had reported the group to authorities more than 1½ years ago.

''The AVN do not comply with the law and the state government is not enforcing compliance,'' he said.
