The $38 million entertainment program featured acts from all over Australia and the world at a variety of custom-made performance venues on the World Expo 88 site from the 10,000-seat spectacular open-air River Stage (for national day events, opening and closing ceremonies and large-scale events), the 850-seat piazza for circus, marching band, acrobatics, magic and mime, and the smaller-scale amphitheatre for national day ceremonies and laser shows. The River Stage was also the venue for the popular evening fireworks and large-scale laser show, set to music, each Expo evening at 10 pm.
