‘Ridiculous scenes’

starts on February 8.

Djokovic, the reigning Australian Open champion, is among a select group of stars - including Serena Williams, Naomi Osaka and Rafael Nadal - flown into Adelaide to enjoy better facilities such as hotel rooms with balconies, unlike the majority

However, Australian Open tournament director Craig Tiley defended Djokovic, saying his letter merely contained 'suggestions and ideas', not demands.

Tiley said Australia's strict quarantine rules were initially a 'shock' to some players but most had told him during a conference call that they accepted the restrictions and wanted to apologise for the comments of a disgruntled few. "The majority of the players have been absolutely fantastic and this is a playing group that's a little bit upset with what some others have said because it holds them in a bad light in the community," Tiley said.

He also ruled out cutting the maximum duration of men's matches from five sets to three to help players whose preparation had been compromised by quarantine lockdown.

"We haven't entertained those comments or that position," he said.

Meanwhile Kyrgios also took aim at fellow Australian player Bernard Tomic's girlfriend, Vanessa Sierra, after she complained in an online video about cold food and having to wash her own hair in quarantine.

"I don't mind Bernie but his Mrs obviously has no perspective, ridiculous scenes," Kyrgios tweeted.
