The Morrison government says Australia is on standby to assist the United States with an extension of its extraction mission from Kabul's international airport.
Foreign Affairs Minister Marise Payne on Monday said defence personnel were awaiting orders by US officials to extend its withdrawal efforts from Harmid Karzai International Airport, following the takeover of Afghanistan by the Taliban a week ago.
"We are part of those discussions, and if they ought to be extended we are absolutely ready to support a continuing operation at Harmid Karzai International Airport," Ms Payne said.
"The last 24 hours, we have evacuated over 450 people from Kabul on those four ADF flights."
Ms Payne confirmed 271 Australians and Afghani visa holders have already been brought to Australia, including 175 people arriving in Melbourne on Monday morning.
During Question Time, Prime Minister Scott Morrison said any new Afghan government would be held to account with regards to human rights, especially for women and girls.
He also noted the Australian Defence Force was attempting to extract citizens, permanent residents and visa holders from one of the most extreme conditions ever operated in.
"These evacuations are both dangerous and complex landing slots in Kabul, are limited, and the on ground time is also," Mr Morrison said.
Roughly 1000 people have been extracted from Kabul from Australian aircraft and include Australian, UK and New Zealand citizens and a number of vulnerable Afghans, including women, children and Hazaras.
Evacuees also include local Afghan staff such as interpreters who have assisted Australian military operations during the past two decades of conflict in the central Asian country.
Mr Morrison also reaffirmed during Question Time the 3000 spots to Afghan refugees was floor and would increase Australia's annual refugee intake if necessary.
"We will be resettling people who have legitimate claims through our official humanitarian program," he said.
"We will not be providing a pathway to anyone who seeks to come here by any other means."
The prime minister also confirmed a cohort of countries including Australia are in discussion about expanding processing capabilities, to get more people into the airport and onto planes.
Ms Payne noted the situation remains volatile and access to the northern gate of the airport remains closed.
"The most significant challenge continues to be access to Harmid Karzai International Airport," she said.
"As we've seen from reporting and as we know from our people on the ground, this is a situation that remains extremely volatile and very dangerous.
"Our officials on the ground are literally in constant discussions with the US with NATO representatives about the best ways to move people into the airport."
National Security Cabinet is meeting daily in regards to the events occurring in Afghanistan.
Labor opposition leader Anthony Albanese said the task to rescue people from Afghanistan is an almost impossible task.
"Providing support to those who supported Australians on the ground is more than just a moral obligation, it is a national security imperative," he said.
"I do not understand why a team of the kind that we only recently deployed was not in place in Kabul, the day the government announced Australia's intention to leave, nearly three months ago.
"No one has been hurt as much as 39 million people in Afghanistan, especially women and girls who will be forced to live under a Islamist theocracy, with a history of extravagant and often deprived violence."
Both sides of the chamber paid tribute to fallen soldiers and veterans from the 20-year long conflict, which was sparked after the September 11 attacks on the United States.
"I think a difference has been made to Afghanistan but whatever is the future for that country, the deeds of our service men and women now belong to Australian history, they honour, all of us," Deputy Labor leader Richard Marles said when providing a statement.
Defence Minister Peter Dutton said Australia's involvement had assisted in the better livelihoods for many Afghan citizens.
"It is important for us to recognise that their sacrifice has made a significant difference to the lives of those in Afghanistan. A generation of young women and girls who otherwise would have faced certain brutality," Mr Dutton said.
"I want to say thank you very much to the serving men and women of the Australian Defence Force and other agencies in Afghanistan in Kabul right now. The stories of bravery will become obvious to Australians over the coming days and weeks."
