They're probably the same as us. They're a little bit tired. They're a little bit anxious. They have confidence that we've going to safely bring them up. Nevertheless, they'd like to see them sooner rather than later.

Their confidence is so high and the tables have really been turned on Australia. It shows the character that Australia have got that they're still hanging in there going into the fifth Test.
