More than 1100 people have died and dozens of villages ravaged in the worst floods to hit Pakistan since 1929.
Foreign Affairs Minister Stephen Smith said the floods, which occurred between Wednesday and Friday last week, had caused widespread damage to infrastructure, livestock and property across the country.
Mr Smith has announced that Australia will provide $2 million of humanitarian assistance through the United Nations managed-Pakistan Emergency Response Fund and international Red Cross/Crescent Movement.
An additional $3 million package will be provided to help humanitarian agencies, including Australian non-government organisations in Pakistan, to aid with recovery and rebuilding.
Mr Smith said the risk of water borne diseases, including cholera, remained a great concern.
He said approximately 150,000 families required immediate emergency assistance such as food, clean drinking water, tents and medical services.
