About PrivateInvest


PrivateInvest, as a family office driven initiative, has established and solidified itself as a platform to provide wholesale and sophisticated investors investment opportunities through its commercial investment and its lending to commercial borrowers in the Australian commercial property sector

We focus exclusively on commercial real estate opportunities, using an approach which prioritises collaboration, engagement, and direct relationships to mitigate risk and create value for all stakeholders.  

We are big enough to offer you the expertise, industry leadership, and governance expected of any major financial institution, but are small enough to ensure both our borrowers and investors have direct access to all team members when required.   

We provide tailored financing solutions to qualified borrowers in the middle development market segment and our lending is supported by a qualified team who take a genuine interest in supporting our investors and borrowers. 

By delivering on what we believe in, PrivateInvest has returned to its investors above industry average risk weighted returns, with no loss of capital or impairment in any of our Funds and a growing number of borrowers continuing to provide quality, repeat, and successful financing opportunities to PrivateInvest.  

Our goal is to maintain your trust in us to be a complete fund manager and private capital partner in the Australian commercial property sector.    

Our Team - The Thinking Behind The Money

Our specialist finance team has decades of property experience in structuring first and second mortgage debt and preferential equity at leading investment firms and institutions. We are uniquely placed to identify, assess, and work with qualified borrowers seeking finance for a range of development, construction, and other property projects across Australia. Our borrowers have direct access to decision makers and support networks at all stages of their property projects – this sets us apart from larger banks and financial institutions.  

Our Trustee Board of Directors, technical management team and Investment Review Committee are well placed to identify the right loan opportunities and assess the credit risk profiles – providing oversight of the risk management frameworks and execution strategies.   

Through the experience of our team, its focus on transparency, oversight, collaboration, and governance, PrivateInvest has established a funds management company that is big enough and small enough to deliver property finance solutions for all stakeholders.  


When PrivateInvest was created over a decade ago, our goal and promise was the same as it is today: to be a transparent, trustworthy, and forward-thinking values-based investment business with a strong culture that is always challenging the status quo, leveraging its best asset, its people, and producing above industry average risk weighted returns to the benefit of all stakeholders.
