The redress scheme for survivors of child sexual abuse in institutions is due to start in 2018, although key players including the states and territories want the full details before deciding whether to join it.
Attorney-General George Brandis and Social Services Minister Christian Porter will brief state and territory attorneys-general later in May about the details of the opt-in scheme and hold a similar briefing for non-government organisations.
"We continue to encourage the states, territories and non-government institutions to maximise the impact of the scheme by opting-in on a 'responsible entity pays' basis, which will ensure the best possible redress scheme for survivors," they said.
The federal budget has committed an initial $33.4 million to meet the scheme's establishment costs.
A dedicated telephone helpline and website will be available from March to provide information about the scheme.
It will also provide information about legal and community support services now provided through the child sex abuse royal commission, which delivers its final report to the federal government by December 15.
Those services will continue to be funded to support the scheme, the government said.
Survivors of child sexual abuse in Commonwealth institutions will be able to apply for redress from July next year.
Under the Commonwealth scheme, survivors will receive payments of up to $150,000 as well as psychological counselling and, if requested, a direct personal acknowledgment and response from the institution involved.
