Introducing a true merger partner

When considering the next phase of your business, it's important to work with a partner who shares your commitment to building trust with your clients and investing in the people who have helped you build a successful and highly regarded business.

From our humble beginnings over 95 years ago, Gallagher has grown into a global operation helping businesses large and small face their future with confidence. The family values which founded our business continue to drive the way we think and operate today.

Since we acquired OAMPS in 2014, expanding our Australian operation, we've been building our reach and capability through strategic investments in brokerages across the country.

A merger is a personal and a business decision; at Gallagher we treat it as such. Our ethos is for you to become our colleagues, not a 'hub' we oversee. Your business and your employees will have a opportunity to grow with a brokerage that is large enough to compete on a global scale, but agile in our thinking and approach.

Be part of our story

Founded by Arthur J. Gallagher in Chicago in 1927 and listed on the NYSE in 1984, Gallagher has grown to be a leading insurance brokerage, risk management and consulting company. With significant reach internationally, our organisation employs over 52,000 people and our global network provides services in more than 130 countries.*

In Australia, we've become the chosen partner to clients from small family run businesses through to multinational corporations.

The Gallagher network of regional and metropolitan branches across Australia means we're connected to local business communities because we're part of them ourselves, helping us better understand the unique risks and needs of every business we service.

Our people form part of those communities too and we're dedicated to creating an inclusive and nurturing environment for every individual. We're proud to be a gold certified Mental Health First Aid skilled workplace and a Top Insurance Employer recognised by Insurance Business Magazine.
