Our Story

Sim & Mack was born for an Australian active life, inspired by the beauty of the world’s only island continent, from its magnificent coast to its unforgiving red centre.

Founder Andrew McKenna, a 5th generation Australian married to a 3rd generation Singaporean, Simran Sidhu, wanted a clothing label to capture the essence of Australia – the unique spirit of the world’s oldest indigenous culture and an ever evolving mix of migrant cultures.

The development of Sim & Mack began in 2021 as McKenna embarked on a plan to realise a long-held dream for a new generation Australian made active leisurewear label. Beginning without a background in fashion, he was fortunate to receive chance introductions to two Adelaide based designers and from there, took his first steps. With valued support from several others who backed his vision, McKenna produced Sim & Mack’s inaugural range for release in 2023.

As a small family business, Sim & Mack wants to grow with its customers into a viable alternative to corporate fashion houses. Along the way, achieving even more with respect to sustainability and traceability as they continue to grow in importance to our collective future.
