Officials hope to lure at least a dozen of the world's top-15 tennis stars back to Australia for the season-opening United Cup as player interest soars for the popular mixed teams' event.
Greek fan favourites Stefanos Tsitsipas and Maria Sakkari, China's 2023 Australian Open runner-up Zheng Qinwen and Norwegian star Casper Ruud are the first big names to commit to the third edition of the $15 million showpiece.
Alex de Minaur is almost certain to once again lead tournament hosts Australia while nine-time Australian Open champion Novak Djokovic is also in organisers' sights.
