Help Hev Go To Australia

Hi everyone!
My name is Heaven. I am 11 years old and I live in Key West, Fl.  I need your help.

I have been accepted to become a  People to People ambassador on their summer trip "Reef and Beyond" to Australia.  This is a once in a lifetime opportunity to experience the culture, people and wildlife with expert educational guides.  I will get to swim in the Great Barrier Reef, go backstage at  the Sydney Opera House, experience daily life during a home stay with a local family, feed a pod of dolphins, cuddle with a koala, learn to throw a spear and a boomerang with an aboriginal guide and learn to surf on one of Australia's beautiful beaches.
I am doing as much as I can to earn the money myself, but I know I will need some help.  If you think you can help me with my travel expenses to Australia I would greatly appreciate it.
Thank you so very, very much!
