What Australian Christian organisations hold fundraising events like 40 Hour Famine/Operation Christmas Child?

Are there any other Australian Christian organisations (ones who focus on spreading the Word, giving out Bibles, etc.) that hold special events to raise money for causes? There is, of course, World Visions' 40 Hour Famine and Samaritan Purse' Operation Christmas Child. But, are there others where people (especially, kids) can get actively involved in helping to raise money for Christian causes, unlike organisations who just welcome financial donations and prayers? If any one has any suggestions, it would be most appreciated. Thanks so much!
