Volunteering in Oz?

Hey there,

I'm wanting to do some volunteering whilst i'm here on my year out in Oz (i've been here for 5 months already) preferably with indigenous communities but i'd also like to do some conservation stuff as well. I'm having trouble finding any info on the web, the most that's coming up is WWOOF, which i've already done, but i'd like to do something a bit more helpful.

If you know of anything or have done something like this, please let me know.

Thanks in advance,

Jess
