Scott Morrison has condemned "sickening and untrue" Taliban claims that 41 Australians died in vain during the Afghanistan war.
The prime minister blasted the comments from Taliban spokesperson Suhail Shaheen, who made the incendiary remark earlier in the week.
"It is sickening and untrue, but I'm not surprised about a dishonourable statement from the Taliban," Mr Morrison told reporters in Canberra on Friday.
"They should know that the world is watching them and they expect them to live up to the statements they have made."
He said Taliban commitments to allow people safe passage out of Afghanistan needed to be honoured.
"Trust matters," the prime minister said.
"We will be seeking to ensure in everything we can do to ensure they seek to establish that trust because, at this stage, the account is in deficit with any trust you could put in the Taliban."
The issue of Afghanistan's future was discussed in a phone call between Mr Morrison and US President Joe Biden on Friday.
White House press secretary Jan Psaki said America was incredibly grateful for Australia's partnership during the two-decade conflict.
"I would say and the president would say if he was standing here that those 41 Australians did not in vain," she told reporters in Washington.
"We're incredibly grateful for their support over the course of a 20-year war and Australia remains a pivotal partner to the United States."
