Australia's Olympic chef de mission Kitty Chiller has singled out Tennis Australia when reiterating her tough-line stance towards misbehaving athletes.

Chiller says she will send any troublesome athletes or officials home regardless of their sport, which should come as a warning to young Australian tennis stars Nick Kyrgios and Bernard Tomic who continue to bounce from drama to drama.

The caution comes in the same month Kyrgios and Tomic were involved in a spat surrounding the former's failure to play in Australia's most recent Davis Cup tie against the US.

Kyrgios was involved in further controversy this week when he copped a point penalty for an audible obscenity, before arguing the case further with the umpire.
