Britain's Johanna Konta continued her remarkable Australian Open run with a straight-sets win over China's Zhang Shuai in the quarter-finals.
The unseeded 24-year-old won 6-4 6-1 to become the first British woman to reach a Grand Slam semi-final since Jo Durie made the US Open last four in 1983.
Konta, ranked 47th, will now face German seventh seed Angelique Kerber.
"I'm just so happy that I'm enjoying what I'm doing," said Konta. "That is me living my dream."
Her achievements so far have guaranteed her prize money of at least £370,000 and are likely to secure her a place in the world's top 30.
