Seba’s Song

That inverts the entire logic of the Australian Big Thing. Every other object in this catalogue exists to be seen from a moving car – height, colour and roadside position are the whole design brief. Dambo's Giants are built to be hidden, and the walk is part of the work.

This one is four metres of recycled wood overlooking the Dawesville Cut, reached by a Grade 1 return trail from Estuary Place and also visible from some boat tours.

Dambo builds his giants worldwide from scrap timber – pallets, fence palings, demolition waste – and they weather, grey off and eventually decay, which he treats as intended rather than as failure. Against a catalogue of fibreglass built to outlast everybody, a sculpture designed to return to the ground is a completely different attitude to permanence.

The Dawesville Cut is itself an engineered thing: an artificial channel opened in 1994 to flush the Peel-Harvey estuary, which had become badly degraded by algal blooms. A giant seated above it is looking out over one of Western Australia's larger pieces of environmental repair.

Mandurah's trail has made the town a destination in a way its estuary alone did not.

The year this Giant was installed is not recorded here.
