Child sex abuse survivors worried they will die before getting compensation are counting down the days until the national redress scheme opens on July 1.
The Anglicans, Salvation Army, the Scouts and the YMCA on Thursday joined the Catholic church in promising to sign up for the $3.8 billion scheme.
Survivors who fought for the royal commission and had waited for the scheme to open said they were already asking for forms to fill out.
"They are extremely anxious that they won't be alive to see their redress. Our oldest member is 95," Care Leavers Australia Network chief executive Leonie Sheedy told AAP.
She said there were mixed feelings about the scheme, and how long it had taken to begin.
"People have died. We've lost 34 care leavers since the royal commission was established," Ms Sheedy said.
The scheme will now cover four out of five child sex abuse survivors.
Prime Minister Malcolm Turnbull said the royal commission had allowed survivors to be heard and believed, many for the first time.
"This week, as a nation, we have taken several important steps in the journey of healing," he told parliament.
Social Services Minister Dan Tehan said those who had yet to sign up would be judged by the public and he thanked those who had.
"(Thanks) for owning up to past wrongs, to owning up to behaviour that can only be described as despicable and deplorable, to turn a page," he told reporters..
The Anglican Church reached an "in-principle agreement" to join, and will form an independent entity to cover Anglican dioceses, schools and welfare agencies.
The dioceses of Melbourne, Brisbane and Tasmania have already resolved to join and others are expected soon.
"We think this will be a very important part of the process for the healing of survivors of abuse," Bishop Stephen Pickard told reporters.
The YMCA also said it was working with all 19 YMCAs across Australia to help ensure it can be part of the scheme when it begins.
"We can't change the past for survivors but we can change their future," YMCA Australia chief executive officer Melinda Crole said.
Scouts Australia chief commissioner Neville Tomkins praised the government for providing the scheme to recognise the impact of "horrific crimes", while Major Brad Halse said the Salvation Army was "profoundly sorry" for the abuse children suffered
Mr Tehan said the scheme could begin on July 1 if it passed the Senate.
The Catholic Church estimated it will itself be liable for about $1 billion in compensation.
Mr Tehan was hopeful the last state yet to join, Western Australia, would sign up in the next two weeks, after reaching an agreement with state attorney-general John Quigley.
The scheme will cover about 60,000 institutional child sexual abuse survivors nationally, with compensation payments capped at $150,000.
