The Australian Open qualifying matches were scheduled to begin on Tuesday (January 14) but smoke from the bushfires has blanketed the city of Melbourne and forced the games to be delayed.
The matches were to start at 10am local time but were pushed back by an hour.
The CEO of Tennis Australia defended their decision:

"As you all know and I say this consistently is the health and well-being of, not only the players, the fans, our staff is of utmost important and any decision we make will be around that, the health and well-being of that group."
The grey haze was so thick health officials in the state of Victoria also issued a public health warning:

"So smoke today in Melbourne is in the very poor to hazardous range. When you get to the hazardous range really anyone can develop symptoms.

Players are pledging money to the cause, including Serena Williams who donated her earnings after winning the Auckland Classic on Sunday.
And a campaign under the hastag #Aces4BushfireRelief is encouraging players and individuals to raise funds for every ace served to relief and recovery efforts.
Meanwhile as Tournament organisers monitor conditions in the lead up to the Grand Slam, along the Yarra River rowers and runners were out as normal, grinning and bearing the smokey haze.
