Examining data for Australia and 101 trading partners that span the years 1989–2000, we find immigrants from nations afforded preference under the White Australia policy exert greater proportional influences on Australian imports from their home countries compared to immigrants from nations not privy to such preference. Immigrants from this latter group of countries influence Australian exports to their home countries proportionally more than do immigrants from the former group. We also find immigrant‐trade links vary across disaggregated measures of trade. The results suggest that cultural diversity, affected here by immigration policy, is relevant to a nation's trade patterns.
