Shamrock Shirts is a small family business located in the Hawkesbury district of NSW. We are an online store with no physical bricks and mortar shop. But don't worry, just because we can't meet face to face doesn't mean we don't want to talk to you!

If you have any questions about our products, or you'd like to speak to us about custom merchandise printing or a new car design for a t-shirt, please get in touch. We'd be happy to talk to you about your clothing printing needs or just have a chat about whatever's on your mind.

Use the contact form below if that's easiest. Or you can email Natalie at

If you're returning clothing for a size exchange, please post it back to us on the address below. And make sure you used a tracked mail service so that you know it got here safe and sound. And don't forget to enclose an Exchange Form with your parcel.

You can send us your mail or clothing returns to:
