This question hinges on which countries account for the largest shares of Australia’s total trade, meaning the combined value of what Australia exports to and imports from each partner relative to its overall trade.

China stands out as the biggest partner because Australia sells vast amounts of iron ore, coal, and other resources to China, making that bilateral trade the largest share of Australia’s total trade. The United States is next, reflecting a large and broad economic relationship that includes substantial trade in goods and services.

The other options represent important partners, but their combined share with Australia is smaller than the shares held by China and the United States, so they don’t rank as the top two.
