Your Digital Card
Collection Starts Here!

COMCA is Australia's dedicated marketplace for buying, selling, storing, and managing trading cards - all in one place. It's built for collectors who want speed, trust, and simplicity, without the headaches of traditional selling platforms.

To list on COMCA, you first purchase Submission Credits. Our credit system rewards bulk listers with better value. Once you have credits, simply open the Card Submission Form, enter your details, and submit your cards for processing.

COMCA stands out because it is built specifically for Australian collectors, giving them a faster, safer and more streamlined way to buy, sell and store trading cards without the hassles of overseas marketplaces. Unlike generic platforms, COMCA offers local warehouse storage, bulk listing tools, verified card imaging, and a collector-first experience that removes friction at every step. Sellers get simple listing options, low fees, fast payouts and the ability to store cards so they never have to pack or ship unless they want to. Buyers get trusted listings, clear photos, local delivery and no import taxes or international delays. At its core, COMCA is built by collectors who wanted a fair, transparent, no-BS marketplace designed for the way Australians actually trade cards - modern, secure, and built for speed.

Once your items arrive, they are sorted, scanned, and stored in our secure warehouse. Every card is documented in your COMCA account and organised by sport, year, set, and series for fast picking and accurate order fulfilment.

COMCA charges a 13% commission on all sales. This fee is taken from the final sale price of the item or items sold.
