BRISBANE: If it’s a new year, it must be serious tennis time Down Under. Just over six weeks since the ATP and WTA held their respective 2025 Finals, players on the men’s and women’s tours are arriving in Australia and New Zealand for a crammed two-week schedule of tournaments ahead of the Australian Open, the year’s first Grand Slam event starting Jan. 18 in Melbourne. Leading the way is the United Cup, a mixed teams event which will be played in Perth and Sydney beginning Friday and finishing Jan. 11.
