Australians working to eradicate polio will this week meet Abbott Government officials to urge it to keep its $100 million commitment to eliminate the paralysing disease.

Fears that Australia might renege on its five-year commitment to global polio eradication efforts, announced by Prime Minister Tony Abbott last year, have emerged following the December announcement of a further $3.7 billion in cuts to the nation's aid program. The latest cut came on top of a $7.6 billion cut last May and combined represent the largest cut to the program in its history.

The world is on the brink of eliminating the disease, which is endemic to only three countries: Nigeria, Afghanistan and Pakistan.

Africa has not seen a case of polio for more than 6 months, raising hopes of a polio-free Africa for the first time.
