A Bit About Us

Tresidder Insurance Brokers

A Heritage of Technical Excellence

Tresidder was founded in 2009 by Brad Tresidder to realise the opportunity to deliver great outcomes for clients with complex risk management and insurance needs. Prior to Tresidder, Brad was a senior broker in two major broking firms, working with national and international clients.

We have grown the Tresidder team with the same commitment to technical excellence and great client outcomes. Every member of our team brings deep specialist expertise to bear.


Focussed on Commercial Clients

Tresidder is focussed on clients with complex risk and insurance requirements. Whether it is supporting our commercial clients or our private clients, our differential advantage to clients is our ability to understand and respond to their risk management requirements. Our focus on complex clients affords us the time to invest in developing better solutions for them.


Shareholder Owned and Operated

We are a highly specialised team that recognises we will only succeed if our clients succeed. Anyone who joins the Tresidder team has the opportunity to become a shareholder. Currently, ~30% of our team members are shareholders.

A Strong Track Record of Growth

We measure our success by our ability to attract and retain clients. Over the last five years we have tripled our Gross Written Premium under management. This has been achieved by high levels of client retention and being able to better serve the needs of new clients.


Building the Best Team

We hire for experience and relevance to the issues our clients face. Our team now comprises former executives from global insurers such as Chubb, international risk management firms like Deloitte and global financial powerhouses like HSBC.

We hire the cream of the crop from the Australian broking industry and grow our own. In recent years we have had two finalists and one winner of the NIBA Young Broker of the Year award.

We value diversity in all its forms. Our team gender representation is approximately 55:45 Female to Male.

Our Team

At Tresidders, it is our mission to strive to be outstanding in all we do for our clients, our people and our community.
