The Americans who want to see Australia do well

SEATTLE — Some American fans walking toward Lumen Field on Friday morning were playfully jeering their Australian peers whenever they spotted a telltale yellow jersey. But a major driver of the local economy offered a kinder greeting to the visiting team.

Cranes in view of the stadium gates have been outfitted with the Australian flag and a WELCOME message from the Northwest Seaport Alliance, which manages the ports of Seattle and Tacoma, along with dockworkers’ union ILWU Local 19.

The seaport alliance and the labor union representing its workforce are mounting a similar display throughout the World Cup, rotating flags out to reflect the pair of teams that will face off next in Seattle. But keeping the Australians happy is a more urgent cause for Seattle harbor interests than, say, Bosnia and Herzegovina and Qatar.

Australia is one of the ports’ top trading partners, with the 14th largest source of container volume at the Port of Seattle, but ranks much higher when it comes to the dollar value of goods that come from there. (New Zealand, for example, sends more volume to Seattle than Australia but it’s worth only half as much.)

Meat, including beef and lamb, and minerals comprise the biggest categories of goods that Australia ships to the United States, although some of the most valuable exports — gold and pharmaceuticals — are more likely to land at Sea-Tac airport than via the harbor.

The U.S. and Australia have had a free-trade pact since 2005, although President Donald Trump’s tariff regime threatens to disrupt some trade flows. Australia is currently pushing back on its inclusion on an American list of countries alleged to use forced labor in its supply chains, which the U.S. Trade Representative is using as the basis to impose a 12.5 percent tariff.
