Tomas leads his family to collect water in Kenya. Although they are feeling the effects of the Global Food Crisis, your involvement in the 40 Hour Famine will help.

What is the 40 Hour Famine?

The 40 Hour Famine is one of Australia's biggest youth fundraising events. It's a chance to do something real: give up food or something else that really matters to you for 40* hours and raise funds for kids living in poverty overseas.

It's a great way for young Australians to experience what life's like for children who have to go without – every single day.

The 40 Hour Famine weekend starts at 8pm on Friday 21 August and finishes at noon on Sunday 23 August. But if you can't do it that weekend it's fine to choose another date before 30 September.

World Vision Australia started the 40 Hour Famine in 1975 to raise money to help children, families and communities in desperate need. Today, we continue to provide both short-term and long-term support to tackle the causes of poverty.

We believe young people hold the key to freeing the world from poverty. The skills and enthusiasm they develop as leaders are critical in changing the way industry, educational institutions, society and families think about the world. The 40 Hour Famine has become a rite of passage for young, socially-minded Australians where they can learn about fighting for justice.
