Rohingya refugees in Bangladesh camps have threatened to commit suicide should they be forced back to Myanmar.
That's one of the messages from a report Oxfam released on Monday after they interviewed 208 refugees.
The aid group has water and sanitation projects and is distributing food and supplies in the camps near Cox's Bazar.
More than 647,000-odd Rohingya Muslims have fled Myanmar for Bangladesh since a military crackdown in late August.
Villagers were massacred, their homes slashed and burned, women gang-raped and babies deliberately thrown on fires and burnt alive.
The Bangladesh and Myanmar governments reached a deal in late November to start returning people within two months.
"If we are forced to go back we will set ourselves on fire," refugee Sanjida Sajjad told Oxfam.
A 65-year-old grandfather, Nur Alum, was also adamant it wasn't safe to return to his country, where Rohingya people are denied citizenship and face discrimination at the hands of a Buddhist majority.
"Returning us by force - it would be better to throw us in a creek and bury us," he told the aid group.
Women refugees told Oxfam they were worried about a lack of lighting at the camps, and are scared to go to the toilet because the latrine shelters can't be locked.
There is also a shortage of adequate clothing, so some women stay hidden in their tents all day.
Oxfam Australia chief executive Helen Szoke said the humanitarian crisis was at a tipping point.
She pointed out the United Nations appeal for money for aid over the next three months was $365 million short.
The Turnbull government has chipped in $30 million.
