The Trump administration’s new tariffs have extended to the remote Heard and McDonald Islands, located 4,000 km southwest of Australia. These islands, home to penguins and seals, are among the most unlikely places to be impacted by trade tariffs. The islands, which are only accessible via a seven-day boat trip, haven’t seen human visitors in nearly a decade.

The new import tax, aimed at retaliating against trade barriers on US products, also affects other Australian territories like Norfolk Island, Cocos (Keeling) Islands, and Christmas Island. Norfolk Island, with a population of 2,200, faces a 29% tariff, while the other territories are subject to a 10% tariff.

Despite the lack of major exports, the islands are known for their unique ecosystem, including Australia’s largest volcano, Big Ben, and an abundance of wildlife. The islands are a UNESCO World Heritage site, hosting large colonies of penguins and seals.

Experts like Mike Coffin from the University of Tasmania find it hard to believe there are significant exports from the islands to the US, with the trade mainly consisting of minor shipments like machinery. Australia has criticized the tariffs, calling them “unwarranted.”
