Kyle Edmund will try to extend his remarkable Australian Open run and reach a first Grand Slam final when he takes on Marin Cilic on Thursday.
The 23-year-old Briton, ranked 49th, plays sixth seed Cilic in the Melbourne night session at 08:30 GMT.
Edmund is only the sixth British man to play in a major singles semi-final since tennis went professional in 1968.
There will be live text and radio commentary available on BBC Sport from 08:00.
"There's no reason why I can't go out there and put a good level on the court, enjoy the occasion again," said Edmund.
