The Treasure Cup side event runs the day after the Brisbane September Regional at the same venue. Treasure Cups are constructed Swiss events with no top cut, best-of-one, 30 minutes per round plus five minutes of extra time, with electronic decklist submission through TCG+. They are the lower-barrier companion to the regional. [CardPop draft — found by an automated web sweep, not verified against the organiser's page. Start and end times, entry fee and player cap are unconfirmed, and the date is tied to the contested regional date — if the regional moves to 12 September, this moves to the 13th.]
