Tennis bad boys Bernard Tomic and Nick Kyrgios have been put on notice by Australia's Olympic team boss to improve their behaviour if they want to represent their country in Rio.

Chef de mission Kitty Chiller described Tomic's behaviour at a tournament in Madrid this week as "appalling", after he deliberately gave up a match point and said he didn't care because he has $10 million.

She says it goes against the values of the Australian Olympic team.

"Every athlete is under the microscope now," Chiller said on Saturday following the Australian Olympic Committee's AGM.
