A number of Christian superannuation funds are looking at working closer together in an effort to remain competitive with Australia's larger funds.
The current wave of consolidation in the sector has sparked the funds to stick their heads together and see where they can share costs.
"Boutique funds should be considering how and who they can collaborate with in the medium to long term," Christian Super chief executive Peter Murphy said.
"Certainly the Christian funds, of which there are a few, are trying to look at mechanisms to collaborate on a project-by-project basis."
Consolidation for the faith-based funds was difficult, because most members chose those funds for their culture, Murphy said.
However, joining forces on individual projects could lead to some cost savings, he said.
He said several funds were in discussion with each other to see how they could benefit from their combined strength, but it was too early to discuss what form a collaboration would take.
Another faith-based superannuation fund taking part in the collaboration discussions is the Uniting Beneficiary Fund, a $340 million fund for Uniting Church ministers.
"In terms of the overall market that we are dealing with, [it is] forcing funds to look at collaboration or to merge. So it is in that context that it is in Christian funds' interest to be looking at the collaborations," Uniting Church chairman Robert Hoskins said.
"We simply have put a number of options on the table and we will pick them off this year. Certainly in our next meeting we will be looking at firming them up a little bit," Hoskins said.
