Searching for resources (or an expert to Skype) regarding Indigenous Australians & ANZAC Day

Our students are ready to explore some deeper issues surrounding ANZAC day so this year we will be working on the topic of 'The experience of Indigenous Australians in World War.'

I am looking for resources, someone for our class to Skype with regarding this issue, and any ideas teachers out there might have in regards to this topic of study.

So far I have found a few resources.

An article about Australia's first Coloured Diggers March
