Indonesia is considering extending its assistance to more than 1000 Rohingya asylum seekers sheltered there, as Australia is urged to re-think its policy not to resettle them.
In May, boats carrying 1800 trafficked women, men and children landed in Aceh, Indonesia, and hundreds or maybe thousands more died at sea.
Regional governments were slow to respond but eventually Indonesia and Malaysia agreed to shelter the Rohingya people until next May.
Indonesia's Foreign Ministry spokesman Arrmanatha Nasir says there have been talks with the UNHCR and the International Organisation for Migration as recently as this week about extending the arrangement.
"We realise that usual recipient countries, especially those in Europe like Germany and others, at the moment they have an influx of migrants from the Middle East," he said.
"We are taking measures to ... make shelter for them into the longer term.
"We welcome, well, we urge countries, to be willing to accept them permanently."
Testimonies of the asylum seekers' "hellish" ordeals are contained in Amnesty International's new report, Deadly Journeys, released on Wednesday.
It asks regional governments - including Australia - to urgently step up their response to the crisis, with another "sailing season" now underway.
Australia gave around $A1 million in aid but did not assist with search and rescue.
Australia also won't resettle any of the Rohingya, under its policy not to accept refugees who registered with the UNHCR in Indonesia after July 1, 2014.
Amnesty researcher Anna Shea says naval resources being used to enforce that policy through Operation Sovereign Borders could have helped in the Bay of Bengal and Andaman Sea.
"There were dozens of boats containing hundreds of desperate passengers who were not able to land, there was a lot of confusion about where they were and what we desperately needed was search and rescue operations," she told AAP.
"More lives will be at risk in the coming months."
Amnesty reports the Rohingya "exchanged one nightmare for another" when they fled by boat, facing beatings to extract money, and weeks of inhuman and degrading conditions at sea.
