 Lang Park in Brisbane is currently (as of 2020) the only purpose-built rectangle stadium in Australia (with fixed seating) with a capacity exceeding 50,000.Stadium Australia is soon to undergo a major renovation which will convert the facility to rectangular-only (though still with movable seating); once the project is complete (expected in 2023), it will have a capacity of 75,000.The first real departure from the multipurpose stadium design occurred in 1972, when the Jackson County Sports Authority in Kansas City, Missouri, opened the Truman Sports Complex, which houses Kauffman Stadium (named Royals Stadium at the time of opening) and Arrowhead Stadium.
