The prime minister has faced mounting pressure to allow the children on the island to come to Australia to receive treatment.
"Children have been transferred off Nauru". Anyone who attempts the journey is now sent to remote camps on Nauru and Papua New Guinea's Manu Island for processing.
A report in the Australian newspaper was confirmed by the former attorney general and now High Commissioner to Britain George Brandis, who said he expected there would be no refugee children left on Nauru by the end of the year.
The prime minister Scott Morrison told reporters yesterday the government was quietly making it happen. "It's been done in accordance with our policies, our existing policies".
Refugee advocates welcomed the change for children, 46 of whom were born in Nauru.
"That is, for five years bar the last fortnight, it required us going to court to force the government to bring kids that were suicidal, kids that were at risk of dying as young as six-months of age", he said.
Under a harsh policy meant to deter asylum-seekers from reaching Australia by boat, Canberra sends arrivals to remote Pacific camps on Nauru and Papua New Guinea's Manus Island for processing, barring them from ever resettling in Australia.
"The health crisis in Australia's offshore detention centres gets worse with every day that passes".
The Home Affairs Minister says the main reason children are being taken off Nauru and brought to Australia is because of the cost, not due to medical reasons.
On the weekend, a YouGov Galaxy poll commissioned by the Sunday Telegraph found nearly 80 per cent of Australians wanted the government to move children and their families from Nauru.
"Even when you bring them to Australia, if you leave families with a sense of uncertainty, it is going to be very hard for the children to recover", he added. "We have seen children not eating or drinking for days, in a comatose state".
The Morrison government has indicated it plans to get all children off Nauru by Christmas this year.
"It is good news that the children will be taken off Nauru, something the sector has been calling on for many years".
Government's expectation is people receiving medical assistance in Australia will - after having their health problems treated - be returned to their country of origin, or resettled in the United States or a third country.
The government fears that refugees could use New Zealand as a backdoor to Australia, since New Zealand citizens are free to live and work in Australia for as long as they like.
A YouGov Gallaxy national poll taken last month found 79 percent of respondents wanted the government to take up New Zealand's offer to accept 150 children and their families.
With the Australian government set to lose its one seat majority, it has come under pressure from the opposition, independent MPs and three of its own backbenchers to evacuate the children from their five year exile on Nauru, where one in four are reported to be suicidal.
