The 21 Challenge is your chance to help homeless youth by doing something you love, perhaps something you don't love, or maybe something you've never done before, for 21 continuous days in June.

You might stop using swear words, eating chocolate, wearing makeup or you could start something like going to yoga every day for 21 days, only drinking water or sporting a crazy hairstyle.

The 21 Challenge starts on June 1st and finishes on June 21st, the longest night of the year in the southern hemisphere and one of the most difficult nights for young people living on the streets.

Participants raise funds while undertaking their Challenge with all the benefits of their efforts going towards Open Family Australia's Outreach programs to benefit at-risk and homeless young people.
