Mr Innes (Australia's race relations commissioner) says what Australia needs is a strong multicultural policy to address these issues.
"Multiculturalism has fallen off the agenda in the last 10 or 12 years and we need the government to come forward with a strong multicultural policy and with strong moral leadership that challenges racism."

Sean's suggestion of researching Anglo Australian folk music and song seems a good idea to me. It could be that you can contribute something of value to this forum. As far as I know there is no-one here who claims particular expertise in that area.
