Shamrock Shirts was established in 2008 and is based in Sydney, Australia.
The company is run by people passionate about what they do, and with nearly 20 years experience in the motor industry and merchandising, our passion for anything with an engine shows through in our unique designs. Our t-shirts are born from our neverending quest to come up with something a bit different, and our shirts are not something you'll find mass-produced in someone's bargain bin sale.
Shamrock Shirts now has Australia's largest range of automotive t-shirts, and that range is growing everyday. Above all, we are about putting a smile on your face ... and we love doing that.
