Abuse survivors are facing further delays to redress payments after negotiations over how to fund compensation for victims of sexual abuse in sporting institutions stalled.

State and territory governments have been under pressure to step in to fund the compensation owed by organisations that refuse to join the National Redress Scheme for victims of institutional sexual abuse.

The ABC has confirmed all states and territories except the Northern Territory supported the move during a virtual meeting on Tuesday.

Without all jurisdictions on board these cases can't be finalised.

It comes as six organisations were added to the "name and shame" list of groups that refuse to sign up to the redress scheme.

The majority of the now 12 organisations named on the list are sporting groups that, unlike religious groups, can't be threatened with having their charity status revoked if they don't join.

Federal Social Services Minister Amanda Rishworth, who led Tuesday's session, would not comment on the details of the meeting.

At least 50 survivor applications are unable to progress, with a number of victims having waited almost eight years since the scheme was established in 2018.

Ms Rishworth wrote to all state and territory ministers last month, unsuccessfully attempting to negotiate a resolution ahead of Tuesday's meeting.

Advocates for survivors of institutional abuse said the issue must be urgently addressed.

Clare Leaney — CEO of In Good Faith, which supports abuse victims — said if sporting groups won't join the scheme they should be cut off permanently from government grants and funding.

"If this is how sports organisations handle disclosures of past harms, what faith can we possibly have in their ability to handle child safety in the future?" she said.

Currently, if an organisation named in an application to the scheme and does not sign up within six months there are temporary restrictions placed on access to government grants.

Ms Leaney said with few levers to pull to force sporting groups onto the scheme, state ministers administering it must stump up the money urgently.

"I believe survivors would expect that all states and territories would fulfil this role where their organisations are unable or cannot do so."

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."

Last month, a parliamentary inquiry recommended the scheme be extended beyond 2028 to meet demand.

The ABC has approached all state and territory ministers responsible for the scheme for comment.
