Nick Kyrgios and Thanasi Kokkinakis remain unfazed after claiming they were threatened with violence following their win in the Australian Open men's doubles draw on Friday.
In the wake of the second-round victory over top seeds Nikola Mektić and Mate Pavić, Kyrgios tweeted that a coach and trainer associated with the Croatians wanted to "fight" the Australians.
It followed an animated match in front of a boisterous packed crowd on Kia Arena, which Kyrgios and Kokkinakis won 7-6 (10-8), 6-3.
They had whipped the crowd into a frenzy, with Pavić later complaining about the behaviour of the spectators.
Speaking after their third-round win on Sunday, Kokkinakis said both he and Kyrgios had shared a laugh about the alleged incident.
"It was pretty funny, I'm not going to lie. Me and Nick, trying to be professionals, so we went in the gym after our doubles match, maybe one of the first times ever," he said.
"I'm going to be honest, it was Pavić's fitness trainer and he came up and he smashed a foam roller against a pole as hard as he can and I thought he was kind of joking. I wasn't sure if he was about to berate his players.
"He came up to Nick and said we were being disrespectful. Nick hit the opponent with a ball, but that's normal, these doubles players have got unbelievable hands so you have to go at them.
Kokkinakis said the Olympic and Wimbledon champions were sore losers.
He said he and Kyrgios would not apologise for the entertainment they bring when they play doubles together.
"It was just our energy and I think at the end of the day they were a bit salty they lost because they've won their fair share of tournaments," Kokkinakis said.
"I don't know, I thought they would handle losing a little better than that, but at the end of the day we're just trying to entertain the crowd.
Kyrgios added: "[I] Just enjoyed it flat out."
Kokkinakis and Kyrgios reached the quarterfinals of the men's doubles draw after defeating 15th seeds Ariel Behar and Gonzalo Escobar 6-4, 4-6, 6-4.
They play sixth seeds Tim Pütz and Michael Venus in the last eight.
