Not in 2006. "Ronaldinho"? He scored later vs Croatia. So maybe it was by "Roberto Carlos"? He didn't score. Actually I think the second goal was by "Cicero"? No. Let's quickly search memory: Brazil 2-0 Australia 2006 goal scorers: Ronaldo (pen) and... "Cafu"? I think the second goal was by "Cafu"? But I'm not sure. I think the second goal was by "Cafu"?
