Jannik Sinner and Madison Keys have begun their Australian Open title defences in Melbourne – and you can follow the first Grand Slam of 2026 across the BBC.

World number two and reigning Wimbledon champion Sinner is bidding for a third Melbourne title in a row.

Top ranked Carlos Alcaraz, who is looking to complete the career Grand Slam, will be one of the main challengers, alongside last year’s finalist Alexander Zverev and 24-time Grand Slam champion Novak Djokovic.

American Keys capped a dream Melbourne run with victory over world number one Aryna Sabalenka in last year’s final.

Sabalenka, a two-time Melbourne champion, will be eager to reclaim her title, while world number two Iga Swiatek goes for a career Grand Slam.

There are no British players left in the singles draws – after Cameron Norrie’s four-set defeat by Zverev – but success could yet come in the doubles and wheelchair events.

There will be comprehensive coverage of the tournament across the BBC – here are the key details.
