What was the 1980s australian song for the ethiopian famine relief featuring the countrys top singers?

Are you refering to "Do They Even Know Its Christmas" by Band Aid? It was the first effort by a compilation of rock singers/bands to focus on the starvation in Ethopia and all of Africa. It was started by Bob Geldof of the Irish band Boom Town Rats. Bono, Boy George, George Micheal, etc all participated.
