Harriet Brown


"I am thrilled to be partnering with Catholic Super. I have been a Catholic Super member for the past few years and have stayed with them as they are number one in investment performance and customer satisfaction.  Many of our values align and I love being an ambassador for such a great company."

At only 27 years old, Harriet is an inspiring, nationally acclaimed athlete, World Ironwoman Champion, Nutri-Grain Ironwoman Series Champion, and Molokai 2 Oahu Paddleboard Champion.

As an accomplished ocean swimmer, Harriet feels she has a responsibility to look after the beaches and oceans, so is passionate about addressing climate change by being conscious of her purchases, reducing her waste, and investing her super responsibly. Catholic Super has always strived to achieve the best investment returns in a responsible way, so a partnership with Harriet became a natural step for us. Through her commitment and determination, Harriet has accomplished incredible things and is keen to inspire and empower others to look into invest their super responsibly.

Starting from very humble beginnings, Harriet found her passion for the ocean at Ocean Grove Surf Club. Growing up, she was involved in many different sports, but ultimately chose Surf Life Saving after seeing her sister take part in the local Nippers program. In 2009, she competed in her first IronWoman Series. In just seven short years, Harriet has become a champion, and is the highest achieving IronWoman from her home state of Victoria.

Harriet’s role as brand ambassador will be to provide an authentic  perspective of Catholic Super, to inspire others to take control of their money (no matter their age!), while emphasising the importance of Responsible Investing.

Harriet is a long-time member of Catholic Super, having found us through her mother, who is also a member and recommended Catholic Super because she knows she can trust us to look after her daughter’s future finances. Harriet’s personal values, including trust and integrity, correspond closely with our own values, making her our perfect ambassador. 

Her personal values, including trust and integrity, correspond closely with our own values, making her the perfect candidate for our ambassadorship.

Catholic Super is proud to support Harriet as she continues to achieve her goals as World Ironwoman Champion, while continuing to provide her with long term financial peace of mind.
