The Northern Territory government has agreed to pay redress to victims of child sexual abuse in sporting institutions, ending a stalemate between states, territories and the federal government.

On Wednesday, the ABC revealed all state and territory governments, except the NT, had signed up to foot the compensation bill left by organisations refusing to sign on to the National Redress Scheme. 

All jurisdictions are required to sign on for the changes to go ahead. 

Twelve organisations have refused to join the National Redress Scheme for victims of child sexual abuse, with at least 50 claims by survivors unable to progress.

The majority are sporting organisations, which, unlike religious organisations, cannot be threatened with having their charitable status revoked if they don't help compensate victim survivors.

Social Services Minister Amanda Rishworth had written to states and territories ahead of a virtual meeting this week, to try and hash out a deal to make their governments funders of last resort.

The NT did not sign on to the deal at Wednesday's meeting, but on Thursday afternoon announced it would now be supporting the change.

In a statement, the acting NT attorney-general Gerard Maley said the government will begin taking the necessary steps to enact the change following territory cabinet approval.

"The NT will not stand in the way of this important issue," he said.

With the scheme facing a substantial backlog, the parliamentary inquiry into its operation last month recommended the federal government increase funding to the Department of Social Services and redress and legal support services to ensure all applications can be finalised on time.

In a statement to the ABC, Ms Rishworth didn't commit to providing additional funding, instead pointing to $142 million over five years announced earlier this year for the scheme's operations.

She also pointed to a new service to support applicants who made incomplete applications.

Ms Rishworth urged the organisations included on the "name and shame" list to reconsider their refusal to join the scheme.

"I call on each of these institutions to do the right thing by survivors of institutional child sexual abuse, reverse their decision and join the scheme as a priority," she said.

"Survivors have waited too long."

Currently, the scheme is scheduled to end in 2028, but the recent parliamentary review into the program recommended it be extended beyond that date to meet demand. 

State, territory and federal ministers have also agreed to increase reporting obligations on institutions.

A statement released by ministers after the meeting said this change look at improving the delivery of direct, personal responses to survivors from institutions.

Ministers responsible for the scheme will meet again in mid-2025.
