Australian Open Organizers on Alert for Return of Bushfire Smoke

The year's first Grand Slam begins in earnest on Monday, but organizers have already come in for severe criticism after letting qualifying continue on Tuesday and Wednesday, with noxious smoke shrouding Melbourne Park.

Fears the smoke would return on Saturday for the final round of qualifying eased on Friday, when the Environmental Protection Agency downgraded the forecast for air quality in the Melbourne area from "very poor" to "moderate".

Several of those who played on Tuesday and Wednesday suffered breathing problems, with Slovenia's Dalila Jakupovic forced to retire after a coughing fit.

Johanna Konta, whose first-round match against Tunisian Ons Jabeur will not take place until Tuesday, said she was uncertain whether she would be able to play if conditions resembled those of earlier this week.

"Today, it's nice," the British 12th seed told reporters at Melbourne Park. "But definitely when the air hasn't been good, it really hasn't been good.

"It's not ideal, and it wouldn't be ideal to play in, that's for sure. I was practicing on Tuesday when it was quite bad, you can definitely feel (it). It's not a healthy environment to play in ..."

Konta's compatriot, Liam Broady, who lost his first-round qualifying match on Tuesday, launched a broadside at organizers on Thursday, describing an e-mail sent to players about the smoke as a "slap in the face".

Tournament chief Craig Tiley said on Thursday he had initially been reluctant to detail numbers to players because of the complexity of the matter but on Friday organizers released full details of their Air Quality Policy.

A discussion overplays being suspended would be held when fine particulate matter (PM2.5) was measured between 97 and 200 micrograms per cubic meter by the monitoring stations at Melbourne Park.

Matchplay would be suspended if that rating exceeded the 200 microgram mark, it said, although referees retained the discretion to "suspend, maintain or resume" matches on advice from medical experts or based on weather forecasts.

If a play was suspended on the three stadium courts, the roof of the arena would be closed until the air quality reached a suitable level.

Organizers said no play or practice had been allowed at Melbourne Park on Tuesday or Wednesday, when the particulate matter exceeded 200 micrograms per cubic meter.

Australia's Prime Minister Scott Morrison on Friday described the bushfires, which have raged since September, killing 29 people and millions of animals, as "an unprecedented series of natural disasters".

Torrential downpours in affected areas since midweek have helped contain the fires but many still blaze, with the possibility of more acrid smoke being blown towards Melbourne.

As in years when soaring temperatures have baked Melbourne Park, however, there was never any real doubt that the tournament, the biggest held in the Asia-Pacific, would go ahead.

"It may look different, but the tournament will happen," Tiley said.
