Coastalline.co

Coastalline is the passion project of Duke, a 13-year-old from the Gold Coast with a big love for design, family, and bold headwear. Raised in a creative household, Duke has always been surrounded by hustle and heart. His Koro, a proud Māori who once played for the New Zealand Rugby League, taught him the importance of heritage and strength. His mum, a designer and founder of Dukies Co, showed him how to bring ideas to life through business.


Inspired by both, Duke decided to follow his own path and launch Coastalline. He built it from the ground up, designing his brand, building his own website, and sourcing manufacturers, all before the age of 14.


In June 2025, he dropped his very first hat: a sports cap boldly embroidered with the word WHĀNAU the Māori word for family. It’s more than just a design. It’s what matters most to him. WHĀNAU is at the heart of Coastalline: staying connected to your people, your roots, and your purpose.


This is just the beginning.

From the Gold Coast to wherever the line takes you Coastalline is made for those who move with meaning.
