Mercer Portfolio Service Superannuation Plan
The Mercer Portfolio Service Superannuation Plan operates as a corporate master trust sitting inside Mercer Super, the superannuation division of professional services firm Mercer, which is in turn wholly owned by Marsh McLennan. The Plan packages a suite of pre-mixed Mercer multi-manager funds for the Australian defined-contribution market. The trustee, Mercer Superannuation (Australia) Limited, is chaired by Jim Minto — one of the region's most recognizable pension governance figures — while Claire Ross runs the broader Mercer Super business as CEO. The Plan's investment architecture draws on Mercer's global delegated-investment capabilities. It offers members access to multi-asset portfolios — including the Mercer Moderate Growth Fund, Mercer Growth Fund, and Mercer Conservative Growth Fund — alongside single-sector exposures such as gold and silver ETFs. Underlying these options sit allocations to real estate, infrastructure, private credit, and a broad range of listed markets, reflecting the firm's house view on diversification. The structure is fundamentally a fund-of-funds for end savers, with Mercer's in-house advisory team selecting external managers across geographies. Marsh McLennan reported approximately $23 billion in total group revenue for 2023 (per the firm, 2024), making it one of the world's largest professional-services enterprises. Within that, Mercer's investment-management and OCIO arm runs hundreds of billions in assets under advisement globally. No stand-alone member or AUM figure is publicly disclosed for this specific superannuation plan. Avanteos Investments Limited has been identified as the successor trustee for a planned fund transfer to CFS Edge (Altss estimate). The Plan's structural differentiator lies in its position as a distribution conduit rather than a standalone fiduciary innovator. Unlike boutique multi-family offices or single-family funds, this vehicle translates institutional portfolio construction — designed by one of the world's longest-running investment consultancies — directly into the Australian compulsory superannuation system, blurring the line between outsourced CIO and retail superannuation provider.

Frequently asked questions
Who is the trustee responsible for the Mercer Portfolio Service Superannuation Plan?
The trustee is Mercer Superannuation (Australia) Limited, chaired by Jim Minto. The wider Mercer Super business is led by CEO Claire Ross, who reports into the Marsh McLennan group structure. The trustee board is ultimately accountable for member outcomes under Australian APRA regulation.
What underlying investments does the Plan offer?
The Plan provides access to Mercer's multi-manager diversified funds — Moderate Growth, Growth, and Conservative Growth — alongside single-sector options such as gold and silver ETFs. These funds allocate across listed equities, fixed income, real estate, infrastructure, and private credit, using external managers selected by Mercer's global advisory and OCIO teams.
How does Mercer Super fit into the Marsh McLennan group?
Mercer Super is a division of Mercer (Australia) Pty Ltd, which is wholly owned by Mercer — the global professional-services firm specializing in investment consulting, retirement, and health. Mercer itself is a subsidiary of Marsh McLennan, the NYSE-listed professional-services group that generated roughly $23 billion in revenue in 2023 (per the firm, 2024).
Is this Plan actively managed by in-house investors or outsourced?
The Plan outsources portfolio construction to Mercer's global investment advisory and delegated-solutions business. Member assets feed into pre-mixed funds that allocate to third-party managers. The trustee board governs the overall structure but does not make direct stock-level decisions for the underlying portfolios.
Is the Plan being restructured or transferred?
Avanteos Investments Limited has been flagged as the successor trustee for a planned fund transfer to CFS Edge, indicating an ongoing transaction or succession event. The precise timeline and terms have not been publicly detailed, though such moves are consistent with consolidation trends in the Australian superannuation master-trust market.
