How does David Malouf use imagery in Great Day?

The dominant image in the story is fire, which appears in the beginning as Ned watches a group on the beach build a bonfire and, at the end, when the museum is set ablaze. The fires provide an ironic tension in the story as they suggest both destruction and positive change. Both the bonfire and the museum fire represent outside forces that have the potential to disrupt the Tyler family, but at the same time, they also provide a cathartic and unifying influence.
