More than 650 Australians and Afghans were evacuated from Kabul airport last night across five flights, Prime Minister Scott Morrison says.
"It was our biggest night," Mr Morrison told Today of the effort by Australian forces on the ground.
"That was on five flights, including one Kiwi flight."
More than 1700 people have now been evacuated from Kabul airport by Australia since the capital fell to the Taliban.
The Taliban has given the western world a deadline of August 31 deadline to evacuate out of Afghanistan.
Mr Morrison said Australians still on the ground in Kabul were doing an extraordinary job of getting people out.
"The people are doing this job on the ground, they are real heroes, compassionate heroes," Mr Morrison said.
"Dealing with people in the most distressing and dangerous of situations.
"Our ADF, our air force flying people in and out, those from three brigades there on the ground doing the job providing security and supporting people getting onto these planes, our Home Affairs officials, our Department of Foreign Affairs and Trade officials, they're going through what is an extraordinarily intense time – and they're getting people out."
Yesterday Foreign Minister Marise Payne said the biggest challenge is getting access to the airport in Kabul.
"This is a situation that remains extremely volatile and very dangerous," she said.
"Our continued focus is on bringing out every Australian and Australian visa holder that we possibly can and supporting those vulnerable Afghanis as well to move if we possibly can."
Meanwhile, the US military is establishing "alternative routes" to the Kabul airport in Afghanistan because of a threat the terror group ISIS-K, a self-proclaimed branch of the Islamic State, poses to the airport and its surroundings.
ISIS-K is a branch of the terror group that first emerged in Syria and Iraq.
