Australia will play for their first Fed Cup title in 45 years after Ashleigh Barty powered the hosts to a thrilling 3-2 win against Belarus in Brisbane.

Barty won both her singles matches before pairing with Samantha Stosur to claim the decisive fifth doubles rubber 7-5 3-6 6-2 against Aryna Sabalenka and Victoria Azarenka on Sunday.

It took the world No.9’s Fed Cup winning streak to 14 and offered Stosur, who had moments of brilliance in the doubles victory, some joy on Pat Rafter Arena after she had lost both singles matches in the tie.
