Australia lost. Its ambassador still won.

SEATTLE — In late May, Greg Moriarty formally presented his credentials to President Donald Trump as Australia’s man in Washington. But it wasn’t until mid-June that Moriarty encountered one of the U.S. officials he most needed to meet: Energy Secretary Chris Wright, whose department plays a key role in critical-minerals deals between the two countries.

Moriarty’s encounter with Wright did not take place at the Energy Department’s headquarters just off the National Mall in Washington, or at any of its many facilities around the country. Rather the men met at Lumen Field in Seattle, at last Friday’s crucial World Cup match between their countries, where Wright led the U.S. delegation — an auspicious occasion for an envoy to make connections in a new post.

“The United States is a very sports-mad country, so is Australia, so [it’s] a great opportunity to get to know them on a different level, because you might touch on one or two items of business,” Moriarty said in an interview. “But it’s generally just so that you can both enjoy the spectacle and the connection that we both have through sports.”

Moriarty also introduced himself to Health and Human Services Secretary Robert F. Kennedy Jr., a figure of particular fascination in Australia given that country’s embrace of harsh Covid-era lockdowns, as well as members of Congress in attendance. Moriarty, a former defense secretary and national security adviser, will work to keep Washington’s foreign-policy establishment focused on the Indo-Pacific in a year when its attention has drifted alternately to the Arctic, Caribbean and Persian Gulf.

“The United States is a superpower. It clearly has global commitments and global responsibilities,” said Moriarty. “But Australia, we think that the United States’s commitment to the Indo-Pacific is very solid.”

In Seattle, however, business was front of mind for Moriarty, who finds himself fighting a new 12.5 percent tariff that the Trump administration has imposed on countries accused of not doing enough to prevent slave labor in their supply chains. At the waterfront Edgewater Hotel, during an event organized by the U.S. Global Leadership Coalition and State Department, Moriarty joined corporate leaders — including Microsoft’s Australian-raised Deputy General Counsel Antony Cook, who has taken a leading role in the company’s approach to AI regulation, and Mikaël Limapalaër of heavyweight pension fund Australian Super — to discuss the future of the bilateral trade relationship.

Moriarty is unusual among Australia’s ambassadors to Washington for not having been a politician — his immediate predecessor, Kevin Rudd, previously served as the country’s prime minister — but he already shows a deft instinct for intertwining economic ties, military alliances and cultural affinity. At one point, he linked a coming National Football League game in Melbourne to the arrival of nuclear submarines as part of the AUKUS security partnership.

“We’re really keen to sort of see how we can use American football to grow an audience in Australia, that will again be really good for the business connections and the people-to-people connections,” said Moriarty.

“Australia will be ready to host the first rotation of U.S. submarines by the end of next year, and we’re hoping that all the Americans who come down to and live down in Western Australia bring their own love of football.”
