Barbara Campbell wants us to follow the birds. Her current show at the Geelong Gallery, ex avibus, retraces the global migratory patterns of wading shorebirds—a new instalment in her longstanding commitment to reconceptualise the (im)possibilities of artistic expression. In this exhibition, these possibilities are doubly explored through an emphasis on the agency of the gallery visitor who, admitted into Campbell’s constructed ebb and flow of a natural homing route, experiences the shorebird’s journey as they walk through the gallery.
