Backpack Indonesia - Group Travel

I am travelling for the first time, backpacking through Indonesia. I plan to set out from Bali, then to East Java, to see the famous Mount Bromo, Ijen Crater and the many wonderful waterfalls around there.
All the sites I will be visiting are in this link: http://www.vacationhomes.net/blog/2011/12/22/top-10-places-to-visit-in-indonesia/

In Bali, would be a little more chill with some diving/surfing if possible in the day and some partying in the night ;) (i am 20 year old from Singapore)!

Looking for backpacking travelers who would like to join me in my venture through Indonesia! As I am from the South East Region, I know a bit about the culture and would even love to travel to Malaysia and Singapore, which i know very well!
