Lowanna.

On Friday evenings, Lowanna walks down to the dock at Port Lincoln. Every week. Rain, southerly wind, or that dry inland heat that sometimes reaches the coast and leaves your mouth parched. Fridays are Fridays.

Five lifeguards and two fishermen. Sometimes six and three, depending on the season. Someone brings an esky — the portable cooler that in Australia is practically street furniture — loaded with beers, water, the odd soft drink. They sit on the edge of the dock with their legs hanging over, or on the plastic crates the fishermen leave leaning against the railing. No table. No protocol. The dock at that hour belongs to them because nobody else comes down.

Port Lincoln has fifteen thousand people. The tuna industry, the harbor, the Neptune Islands seventy kilometers to the south. It's a town where everyone roughly knows what everyone else does, and where the dock at seven on a Friday evening is the closest thing to a bar without walls you're going to find.

One Friday, someone brought up a new operator from Adelaide who'd set up shark tours in the area. "Pure carnage tourism," one of the fishermen said. Lowanna listened. Drank. Didn't say anything for five minutes.

Then she spoke for eight minutes straight. The difference between responsible shark diving and shark baiting, the data on behavioral impact, the protocols that exist and the ones that should. Nobody interrupted. When she finished, one of the fishermen looked at her and said: "You should write that down."

She laughed. "Nah, mate. Just needed someone to hear it."
