Welcome to Coast

Welcome to Coast

We’re thrilled to announce that from today, Trident Marine Insurance will now be known as Coast Insurance.

This change reflects our coming ashore from our origins in marine insurance and transformation into a multi-class underwriting agency, still maintaining a strong marine focus. It’s a coming of age in the year 2021, as we move beyond our roots in the Trident Insurance Group to become a stand-alone underwriting agency, which serves both the broker and direct customer markets.

The new brand truly encompasses our core business values and was formed around the idea of protecting the Australian way of life. We are proud to be recognised as one of Australia’s leading marine underwriting agencies and this brand refresh now best reflects everything we have to offer.

Speaking to our General Manager of Underwriting, Stephanie Muller, she says

“Coast has come about following years of evolving Trident Underwriting into a business which today, has so much more to offer. We are very proud of our roots as Trident and our brand has an excellent reputation, however branching into other areas of insurance creates the need to relaunch with a fresh new face. We are all quite excited about the future and are very focused on what’s ahead of us.”
What hasn’t changed. Our people.

All of the familiar names and faces you’ve dealt with at Trident now make up the team at Coast Insurance.
