Help Sydney go to Sydney

Hi, this upcoming June I will be lucky enough to be able go to Australia with the MS All State Lions Band for Colorguard. While I’m there I will make friends, travel to a different country, and become a better performer. Ever since I was little I have always wanted to go to the place where I was named after. Unfortunately, this trip will be over $5,000 so I would greatly appreciate any help you could give me!! Thank you very much!
