"The Liberal-National government expects all the institutions where institutional child sexual abuse has occurred to sign up to the national redress scheme as soon as possible."
Applications for redress can only be processed after the relevant institution has joined the scheme, leaving many victims still unable to receive compensation.
"As additional institutions join, more applications can be processed and more survivors of institutional child sexual abuse can access support and acknowledgement through the scheme," Mr Fletcher said.
Speaking about joining the scheme, president of the Uniting Church in Australia Dr Deidre Palmer said "this is the fairest way to ensure survivors are consistently and equitably treated and supported".
"I would also like to repeat once more the sincere apology I and past Uniting Church presidents have made to people who were abused in our care as children." she said.
"I am truly sorry that we didn’t protect and care for you in accordance with our Christian values."
The scheme has come under fire from victims' advocates this week, who say it is traumatising survivors and should be overhauled.
Survivors and their supporters will stage a rally in Melbourne on Sunday calling for significant changes to the $3.8 billion scheme.
Victims' advocates calling for an overhaul of the scheme argue the federal government should start again and implement all of the recommendations of the Royal Commission into Child Sexual Abuse in Australian Institutions.
