About COMCA

US Sports Cards Australia (USSCA) began in early 2017 as a small Facebook group created for Australian collectors of US sports trading cards. What started as a niche space for NHL card enthusiasts quickly grew into a thriving multi-sport community. As interest expanded across Baseball, NFL, NBA, WWE and more, USSCA evolved into one of Australia’s most active and trusted trading card groups, now home to 2,500+ passionate collectors.

In 2019, USSCA launched its first website to help members browse available stock, check updates, and stay connected around the clock. The goal was simple: support a growing community with better tools, better access, and a smoother collecting experience.

As the Australian hobby continued to expand, so did the vision. The next step was clear: build a modern, purpose-built platform that could support collectors nationwide, streamline buying and selling, and push the trading card scene forward.

That vision became COMCA.

COMCA represents the evolution of USSCA. A dedicated Australian marketplace designed to make buying, selling, storing, and managing trading cards easier, safer, and more accessible for everyone. Built from the community that started it all, COMCA aims to elevate the hobby and support the next generation of collectors across Australia.
