A number of rape crisis centres may have to close because of escalating cash difficulties.
And differences have emerged between Rape Crisis Network Ireland (RCNI) and the child and family agency, Tusla.
The RCNI says Tusla has withdrawn all of its core funding, amounting to some €240,000.
"There are fears that centres will close, and services will be reduced," said Cliona Sadlier, Executive Director of the RCNI. "By itself Tusla can never get the job of addressing sexual violence done," she told the Irish Independent.
The RCNI's National Rape Crisis Statistic Report will be launched this morning.
Ms Sadlier said it could be the organisation's last such report due to an escalating cash crisis.
Among the key findings were 93pc of perpetrators were known to the victim, while 15pc of attackers were under 18.
