The Living Tongues Institute for Endangered Languages in Oregon, USA has set up a youtube channel in co-operation with The National Geographic’s Enduring Voices project. You can find the youtube channel here. There is not really much info about the Australian language situation on the sites except that obviously, the languages of Northern Australia have been identified as severely threatened. This video shows some of the Enduring voices crew working in Northern Australia including work they did with Charlie Mangulda, possibly the last speaker of Amurdag:
Something I found interesting was a few news stories that have been doing the internet rounds recently about youth from southern Chile who have been using an endangered language Huilliche in mobile phone texting and hip hop music. As we know, the greatest chance of survival a language has is intergenerational use, that is that young people are learning and using the language so it may continue to be passed on. You can read the news stories about Huilliche here and here.
And here is a video from the Enduring Voices youtube channel of some youth singing a hip hop song in a mixture of Spanish and Huilliche.
