The Big Barra

That is a stronger relationship than most produce landmarks manage. A giant apple stands near orchards; this one stands at the tanks.

Karumba is the only town on the Gulf of Carpentaria coast reachable by sealed road, at the mouth of the Norman River, and it exists on prawns, barramundi and live cattle export – plus an enormous seasonal influx of people who drive extraordinary distances to fish. The sunset over the Gulf from Karumba Point is a genuine institution.

Barramundi are also biologically peculiar in a way worth knowing before looking at a giant one. They hatch male, live several years that way, then change sex and become female, so every very large barramundi is an old female fish. Restocking programmes have to account for that.

This is the catalogue's fourth barramundi, with Normanton's six-metre fish seventy kilometres inland, Daintree's on Stewart Street and the Wanguri one in Darwin. All four sit within the species' northern range, and between them they mark how completely one fish defines recreational fishing across the top of Australia.

The sculpture's maker, size and date are not recorded.
