The 23-year-old became embroiled in an expletive-laden rant at umpire Fergus Murphy in his first-round win against Spaniard Roberto Carballes Baena, at one point accusing a line judge of "rigging" his match.
In his second round match later in the day against Canadian Felix Auger-Aliassime, which he lost in three sets, Kyrgios was given another warning by umpire James Keothavong for smashing a ball out of the ground after a call went against him.
Kyrgios, who is never far from controversy wherever he plays, also rowed with fans and a courtside photographer and appeared to be going through the motions in the final games.

He was fine a total of $7,500 for his conduct in the first match and then another $10,000 for his behaviour in the second.
Afterwards Kyrgios described the performance of the match officials as "a joke" and "horrendous".
"I think it's ridiculous. Like, why not have another umpire ready to come in if that guy's have a terrible day?" Kyrgios said. "I don't understand. I have to pay the fines for it.
"The calls are horrendous, but I get fined and he gets nothing. It's like a black star.
"I don't know what happens. It's rubbish."
