The national redress scheme - established in response to the Royal Commission into Institutional Responses to Child Sexual Abuse - will get an extra $39.7 million in grants over two years.
The new grant funding began flowing to service providers who have demonstrated they can deliver the best outcomes for scheme participants on July 1.
More than 15,000 people have accessed support from the scheme since it was set up nearly four years ago.
Social Services Amanda Rishworth announced the funding on Wednesday, saying redress support services were vital to addressing the challenges and barriers child sexual abuse survivors face.
"For many survivors, their redress application is the first time they've told anyone about what happened to them," she said in a statement.
"Additional funding for support services will help them get through this difficult time and ease their journey."
From July 1, 15 new organisations started delivering services, including at least one new provider in each state and territory.
The successful grant applicants also included 28 organisations that provide existing services under the scheme and will continue or expand their work.
The social services department will work with providers who were unsuccessful in their funding bid and transition participants to alternatives, Ms Rishworth said.
