Bali?

Anybody was (or live) in Bali, Java, Singapore or Indonesia in general? (or around these areas) Or even Australia? 

I may have an unexpected trip over there on mid of November.

While being there, I'd love to explore and maybe do a travel photoreportage of Bali (and nearby).

I feel really stressed out since I have to plan out everything in such a very short timing notice. 
I'd be happy to hear for suggestions, recommendations etc. and if anybody kind is living there (couchsurfing) I'd be happy to hang out and learn being there!

PS: As for Singapore, I might have a flight with a day (or two) spent there. I thought to explore there. As for Australia, since being in Bali, I'd be close to it. I've never been there and always dreamt to see that country. But I am not sure if time-wise I can arrange it....
