Great Britain's bid to reach the Davis Cup Finals knockout stage started with a superb victory over Australia as debutant Jack Draper and Dan Evans both won their singles matches.
In the first of a best-of-three-match tie, Draper won 6-7 (6-8) 6-3 7-6 (7-4) against Thanasi Kokkinakis.
Evans beat Alex de Minaur, ranked 12th in the world, 6-1 2-6 6-4 in the second singles match on Wednesday.
Evans is set to play with Wimbledon champion Neal Skupski in the doubles.
While Britain have already won the tie, the doubles result could still prove crucial later in the week when it comes down to clinching qualification.
