About Us

Welcome to Petrol Threads, the reborn, turbocharged version of Shamrock Shirts. If you're new here, buckle up. If you're a returning Shamrock customer, you'll notice we've taken a sharp turn into a new era of automotive apparel. We've taken everything you know and loved about Shamrock and cranked it up to eleven. But fear not, we haven't lost our way. It's still the same passionate team, the same top-notch quality, and the same dedication to delivering you the best damn car clothing in the land.

The Shamrock Era

If you've been with us from the start, you already know our story. But for those just joining the ride, let's rewind to 2007. Our story began in the scenic Hawkesbury district of NSW, with a simple 'I am the Stig' t-shirt and a dream. Seizing an opportunity, and ruffling more than a few feathers in the process, we started life as the official supplier of Top Gear merchandise in Australia. This was to be a partnership that lasted several years, and firmly ingrained Top Gear into our hearts. But being mere suppliers wasn't enough, we soon realised that our true passion lay in creating our own designs. We wanted to give the Australian car scene something different, something that resonated with true car guys. So we started crafting our own designs, hand-drawing each one with meticulous detail and printing them ourselves to ensure the highest quality.

The Evolution: Enter Petrol Threads

Fast forward almost two decades to today, and Shamrock Shirts has shifted into a higher gear, rebranding as Petrol Threads. We felt we needed a new name that truly captured the spirit of our brand and our deep-seated love for everything automotive. But, what's new under the bonnet?

Well, we've taken everything you loved about Shamrock Shirts and cranked it up to eleven. Our design team has been hard at work creating fresh new designs, concentrating now on a small front / large back print structure. And we've expanded our range of clothing. While our men's t-shirts remain the backbone of our collection, it's not just about the men anymore. We've heard your cries ladies, and we've answered. Petrol Threads now offers a range of clothing specifically designed for female car enthusiasts. Being a female-owned and run brand, we think everyone deserves to rock their love for cars, regardless of gender. So ladies, get ready to unleash your inner speed demon and show the world what you're made of.

But we didn't stop there. We know that the love for cars starts at a young age, and we wanted to make sure that the next generation of petrol heads had something to fuel their passion. That's why we've introduced a line of clothing for kids. From toddler tees for the tiniest speedsters to hoodies for aspiring racers. Our kids car t-shirts are perfect for the little ones who dream of burning rubber and leaving everyone else in the dust.

The Same High-Octane Quality

Now, let's get one thing straight. Despite the new name, it's still the same team behind the scenes. We are the same people who poured our hearts and souls into Shamrock Shirts, and we bring that same level of dedication to Petrol Threads. Each design is still lovingly hand drawn, and every print is done in-house.

Our commitment to an ethical supply chain remains unwavering, which is why we continue to partner with AS Colour. Ensuring our products are not only top-notch but also responsibly sourced, kind to the planet and its people. It's a balance we're proud to maintain, and it's something that will never change, no matter what our name is.

The Road Ahead

The road ahead is filled with endless possibilities, and we're excited to have you along for the ride. Whether you're a long-time customer or a newcomer to our brand, we'd love you to share your passion with us, and join a community that lives and breathes motorsport.

Here's to many more miles together. Welcome to Petrol Threads.
