Businessman Dick Smith says a local anti-vaccination lobby group is misrepresenting the issue of immunisation.

Mr Smith has thrown financial support behind a campaign to boost vaccination levels in Australia.

He says vaccination is about risk management and the risks of an illness far outweigh that of the vaccination.

Mr Smith says the Bangalow-based Australian Vaccination Network distributes misinformation and presents itself as an authority.

"They are actually anti-vaccination and they should put on every bit of their material that they are anti-vaccination in great big words," he said.

"They have every right for that belief but they should communicate it clearly so people are not misled."

He says there are risks attached to everything in life but the risks of vaccination are small.

"I think they're choosing not to vaccinate because they don't understand risk management - they are told that there is a risk with vaccination - now everything in life has a risk," he said.

"There's a minute risk but it's been proved all over the world that the advantages far outweigh the risk."
