Australia's Largest Range of Automotive T-Shirts

Shamrock Shirts is a small family business based in the Hawkesbury region of NSW.  We design and hand print all of our car t-shirts in-house and have a passion for anything with an engine (or four legs and a wagging tail!).  We started Shamrock Shirts in 2007 with the aim to provide great quality car t-shirts to the automotive scene in Sydney.  Our designs are subtle, refined and we try to cover a huge range of manufacturers and models.  In doing this, we have become Australia's largest range of automotive t-shirts.  No matter what form of motorsport you're into, or what kind of car you drive, our extensive range of original designs will have something perfect for you.
