Real Life Mermaid in Perth

My world revolves around underwater wonder, specializing in captivating underwater fashion modeling and thrilling stunt work. I’ve had the pleasure of making a splash in numerous movies, TV commercials, and music videos.

In August 2012, I took a deep dive into a groundbreaking venture by founding the world’s very first public mermaid school – Mermaid Kat Academy. In addition to offering mermaid classes in Germany and Australia, I host exciting international retreats for fellow mermaids and mermen, creating a worldwide mer-community.

Based in the picturesque waters of Perth, Western Australia, I’m ready to make a splash wherever you need me. From local hire to national and international bookings, I’m all about bringing my real life mermaid magic to you. Let’s create waves together!
