Both immensely talented Australians are ranked between 50 and 100 but it's Kyrgios, usually seeded at the majors, who the world's top players wanted to avoid in the early rounds.
With Tomic sitting on two match points, the 26-year-old made a decision to try a trick serve, playing a between-the-legs shot over the net and into Kyrgios" service court before bouncing a second ball, seemingly in preparation for a "real' serve.
Tomic won the exhibition 6-3 6-4, with the hit-and-giggle nature of the contest summed up best by a truly outrageous final point.
"I don't think there's ever been a player like BT (Tomic)", said Kyrgios after the match.
Tomic has slipped down the world rankings from a career-high number 17 in recent seasons but has improved recently and won his first title in three years at the Chengdu Open in September. "He won a title past year and it looks like he is carrying a bit of momentum which is good to see... he looks happy, he looks healthy".
"He can make a run at the Australian Open, for sure".
Tomic's first set was nearly flawless, while Kyrgios, who has slipped to number 51 in the world, looked a little underdone and struggled to find some rhythm early on. He broke the world No. 51 Kyrgios in the fourth game of the first set to win it 6-3.
Meanwhile, Tomic, who missed last year's Australian Open, has lofty ambitions for the 2019 competition.
Kyrgios, who was knocked out in the second round at Brisbane last week, was beaten 6-3, 6-4 by friend and fellow comeback candidate Bernard Tomic in an all-Australian battle. "You never want to see a talent like that go down and keep being down". "I count my millions", Tomic told the media last January. "I have to raise my game and play better at the end of the day".
