Second seed Andy Murray is into the Australian Open final after holding off Canadian Milos Raonic in a 5-set battle.
Murray will be up against defending champion Novak Djokovic in the final.
"Yeah, the most important thing for me is to sustain my level for long enough, not just for one set here or there, a few games here or there. I need to do it, you know, for a very long period if I want to get the win. That's my challenge on Sunday."
Five-time champion Djokovic is into the final after downing Roger Federer in the other semi-final.
