Australia has pledged $100 million to help eradicate polio for good.

The funds will be spread over five years and will go towards making countries in northern Africa and the Middle East – where outbreaks have been reported – polio-free.

It will also help Afghanistan, Pakistan and Nigeria, where the disease is endemic.

About $20 million will be provided over the next year to the Global Polio Eradication Initiative for immunisations to fight the disease’s re-emergence.

Announcing the pledge on Sunday, Foreign minister Julie Bishop said Australia is committed to helping finish the job of eradicating polio.
