Johanna Konta survived a deciding tie-break to defeat Ajla Tomljanovic and reach the second round of the Australian Open.

The British No.1 from Eastbourne lost to Tomljanovic in Brisbane earlier this month but produced a fine performance to come through 7-6 (7-4) 2-6 7-6 (10-7).

There was little to separate the pair throughout a tight and big-hitting contest but Konta was rewarded for her aggression in the first-to-10-points tie-break, becoming the second British player after Katie Boulter to win using the new scoring format.

Konta found herself 3-1 down in the opening set without having done too much wrong but fought back to win three games in a row and then played a good tie-break.

The 27-year-old slipped from nine to 39 in the rankings in a difficult 2018 after experiencing burn-out over the final months of the previous season, in which she reached the Wimbledon semi-finals.

The signs have been tentatively encouraging since Konta linked up with new coach Dimitri Zavialoff, a Frenchman who guided Stan Wawrinka for much of his career.

The Argus: She claimed a first top-10 win in 18 months over Sloane Stephens in Brisbane before losing to Tomljanovic (above), and a couple of loose shots, including a wild forehand volley from on top of the net, contributed to a change in momentum that saw the Australian take the second set.

A couple of unwise drop shots put Konta on the back foot in the tie-break but she stayed in touch with Tomljanovic and was rock solid mentally in winning the final three points.
