Notice the different questions. One said "Who SHOULD be the Australian Idol?" and Casey came out on top. The other one was "Who do you WANT to be the Australian Idol?" and Anthony came out on top. That's why it's tricky. If it just went on talent I think Casey would win, but we know it doesn't work that way and all those teenage girls votes may get Anthony over the line. I won't be betting on it though.
