Oakbank Racecourse, also but less frequently known as the "Onkaparinga Racecourse", is home of the Oakbank Racing Club, a club which, until 2009, raced just twice annually, Easter Saturday and Easter Monday at the Oakbank Easter Racing Carnival, and has done continually since 1876, except during World War II when it was held at Victoria Park and Morphettville Racecourse due to the army taking over the facility.
