Naomi Osaka will kick off her first season as a Top 5 player at the Brisbane International, and heading Down Under early has given her the chance to take in the sights...

...and enjoy a rare practice opportunity with a fellow US Open champion, Andy Murray.

"I don’t know why you let me hit with you but thank you," the ever-modest Osaka captioned on Instagram.

Murray was equally effusive in his praise of the Japanese youngster in his Instagram caption.

"I think you missed about 2 balls in 30 minutes...and also for the advice on Japanese!"

Also in view was former Top 10 star Andrea Petkovic, who snapped a selfie with her team on Brisbane's Center Court with a cameo from Osaka's coach, Sascha Bajin.

Meanwhile, the season has just about begun for the game's best players. Wimbledon semifinalist Julia Goerges tweeted a photo from the plane before heading off to Auckland's ASB Classic.

Venus Williams touched down in Abu Dhabi to play a Mubadala World Tennis Classic exhibition with sister Serena.

Still, the off-season certainly went by too quickly for some, like Katerina Siniakova, who tweeted a wistful Christmas photo of her and her dog underneath the tree.
