"The Australian Government's Dollar for Dollar initiative will match each dollar you donate to appeals run by AusAID-accredited non-government organisations (NGOs) working to alleviate the food crisis in the Horn of Africa from 5 October until 30 November 2011. This means for example, if you donate $50 to one of these NGOs, the Australian Government will match it with $50."

You can find the list of NGOs in the link above.
If you were thinking about it but haven't done so, now's probably a good time to make your donation go a bit further.
