Scott Morrison has assured alleged sexual abuse victims of a former Melbourne school principal that they have not been forgotten, as he continues to fight for the woman's extradition from Israel.
Malka Leifer faces extradition to Australia on 74 charges of sexually assaulting female students during her time at Melbourne's ultra-orthodox Adass Israel school.
The 52-year-old fled to Israel in 2008 after the allegations first emerged and the process to extradite her has stalled several times since charges were laid in 2013.
She remains in jail, but there are concerns about the long delay in the extradition process.
Federal Labor and Liberal MPs have combined forces to help alleged victims lobby for her extradition to be fast-tracked, ending the delay.
Two alleged victims, Dassi Erlich and Nicole Meyer, travelled to Canberra to meet with Mr Morrison and Attorney-General Christian Porter on Wednesday.
The prime minister said the pair should be "commended and supported" for their brave campaign.
"We stand with them," he said in a statement after the meeting.
He called for Israel to help resolve the matter "transparently and quickly" and reaffirmed his government's commitment to extradite Ms Leifer.
Mr Morrison said he has raised that commitment with Israeli Prime Minister Benjamin Netanyahu and will continue to do so with the incoming Israeli leadership.
Foreign Minister Marise Payne and Australian embassy officials raise the issue frequently, he stressed.
"The Australian government will be unswerving in seeking justice in this matter," he said.
"We are committed to ensuring all Australian children are safe and protected from abuse."
Ms Erlich says the meeting was "extremely productive and encouraging", with the prime minister assuring them that Ms Leifer's alleged victims "have not and will not be forgotten".
"It feels very validating to have this strong level of support from the AU Government," she wrote on Twitter.
Mr Porter said in a statement the time Israel is taking to finalise Australia's extradition request is "regrettable", but the federal government respects it must follow the requirements of Israeli law.
Earlier, Labor MP Josh Burns and Liberal MP Dave Sharma stood side-by-side to stress the nation's support for Ms Erlich and Ms Meyer.
"This is about making sure that justice is done," Mr Burns said.
Mr Sharma, a former Australian ambassador to Israel, said there had been more than 60 court hearings.
"Yet we seem to be no closer to having Malka Leifer extradited," he said.
"This case is a high priority for Australia and it is one we will be ceaseless in pursuing, and it is one that unless resolved soon will have an impact on the broader relationship."
Ms Meyer said she was not pushing for the extradition on behalf of herself.
"We're trying to send a message to all survivors that even if you have been abused life can go on, justice can be served, and we want to stand strong on behalf of all others, not just ourselves."
