Ashleigh Barty became the first home player to reach the Australian Open women's singles final in 42 years as she beat Madison Keys in straight sets on a jubilant Rod Laver Arena.
Wimbledon champion Barty, 25, won 6-1 6-3 against the unseeded American.
Now the top seed is one win away from becoming the first Australian - man or woman - to win the singles since Christine O'Neil won the title in 1978.
Barty will face American 27th seed Danielle Collins in Saturday's final.
Collins, 28, beat seventh seed Iga Swiatek 6-4 6-1 to reach her first Grand Slam final, less than a year after she had surgery for endometriosis.
