To visit all exhibits at Universalmuseum Joanneum (except for Herberstein Animal World), we recommend to purchase a Joanneum 24-hour, 48-hour ticket or an Annual Ticket (Club Joanneum, Jahresticket, Joanneumskarte Schule). These tickets also include the state rooms of Schloss Eggenberg, which can only be seen via guided tour.
Tickets for individual museums are available on their respective websites. An overview of all museums can be found here.
