Australia’s modern Multi-Family Office.

Helping families achieve what matters most.

Protecting and growing family wealth since 1921.

Mutual Trust provides integrated wealth and professional services to Australia’s most successful families, family businesses, trustees, not-for-profits and individuals.  We build purposeful, long-term relationships with our clients to help preserve and grow their wealth for future generations and their communities.

Building and sustaining significant family wealth and values does not just happen.  It takes careful planning and deep engagement across generations.

We work with our clients to establish a clear shared vision for the purpose of their wealth.  With this focus and alignment, we help them create and execute a family strategy to achieve their Purpose of Wealth for generations to come.

“At Mutual Trust we take the time to truly listen to our families and understand their specific circumstances and their needs. They entrust us with so much more than their finances and we help to achieve what matters most to them – whatever that may be.”

Phil Harkness
CEO and Managing Partner, Mutual Trust

Our purpose

Our purpose

Our purpose is to help families achieve what matters most.

We pride ourselves on:

  • Caring for our families, our people and communities, not just their finances
  • Delivering what they require under one roof
  • Providing pre-eminent independent advice
  • Enabling our families to have a positive impact on society

We do this with people who are excellent, heartfelt, inspiring and principled.

In doing so, we will be the exceptional multi-family office.

Our heritage

Initially founded in 1921 by W.L. Baillieu and his four brothers as a vehicle to provide accounting and trustee services for the Baillieu family, we have grown and evolved over the years to meet the needs of a changing world. In 2017, following the union of Mutual Trust and The Myer Family Company Limited, Australia’s largest Multi-Family Office was formed.
Today, Mutual Trust has over 220 employees and four offices nationally and is the trusted partner to many of Australia’s wealthiest families and individuals.

Your services

Our integrated service model provides the essential services required for families and individuals to protect and grow their wealth.

At Mutual Trust, we take the time to understand each family’s unique Purpose.  We start by uncovering what is most valued by the family and by individual family members, permeating everything from investment decisions to engagement and contributions to the community.  Through listening and understanding what matters most, we develop a personalised roadmap to guide the family on important decisions ahead, achieving greater focus and impact.  Our integrated service model provides the essential services required to protect and grow wealth.

With over 220 professionals, the Mutual Trust team has a deep understanding of family office requirements, investment management, taxation, superannuation, succession planning, financial management, philanthropy and trustee services.

Family office

We always put our clients’ interests first, taking the time to build relationships of confidence and trust and tailoring our recommendations to their needs and aspirations.

There is no such thing as a typical family.  We know from experience that every family and every individual within a family is unique and has different aspirations and motivations.

Nonetheless, significant wealth requires specialist advice.  Whether wealth is created or inherited, we provide a level of service distinguished by discretion and advice, guided first and foremost by what matters most to the families we help.

“A good Family Office will support the family in defining, building and executing on their family strategy, no matter how complex their circumstances may be.”

Jeff Steiner, Partner and Head of Family Office

Wealth Management

We provide high quality, objective advice that is always in the best interests of our clients. We have a proven track record of successfully protecting and growing client assets over multiple generations.

We believe the foundation of a strong investment strategy starts with clearly defining our clients’ financial goals and objectives, risk tolerances, time horizon and specific considerations. From this we develop an appropriate return and risk framework, plus a strategic asset allocation. A tailored investment strategy is then documented with an appropriate asset mix, to meet our clients’ long-term investment objectives.

Tax, accounting, consulting & superannuation

Our team works collaboratively to ensure that financial affairs are structured to optimise tax outcomes including the use of corporations, partnerships, trusts and superannuation funds.

We provide specialised taxation and superannuation advice as well as fulfilling clients’ ongoing compliance requirements. Taxation legislation changes constantly and we closely monitor the legislation and rulings to provide clients with accurate and timely advice.

Through the development of deep relationships and comprehensive record keeping, we provide both business and personal financial accounting, as well as a wide range of ancillary services including bookkeeping services.


Experience has taught us that an intention to give is not enough.  When faced with the vast array of problems to solve and charities that need support, alongside potentially divergent family opinions, it is easy to lose focus and momentum.

At Mutual Trust, we help our families find their purpose by uncovering their personal passions and motivations for giving.  We then activate our deep networks and understanding of the philanthropic sector to curate, develop and steward charitable partnerships with organisations that share these passions and align with your purpose.

We also offer unique, high impact opportunities for co-funding and a platform for you to engage with like-minded peers to share the highlights of your giving journey.

In this way, we support you to maximise the positive social impact of your capital and remove the burden of having to do it alone.

Trustee services

Trustees, Executors and Financial Attorneys are placed in an extraordinary position of responsibility that requires the highest degree of integrity and fiduciary care.  Undertaking this role requires time and expertise in financial and non-financial aspects of families and wealth management.

As a licenced Trustee company, Mutual Trust removes this burden from your loved ones and ensures wealth is transitioned in an orderly and tax efficient manner.

Mutual Trust is a licensed trustee company. We can be appointed as executor, trustee or attorney for our clients.
