Migration induces inbound and outbound tourism flows for a country heavily reliant on migration, such as Australia. Previous research has provided estimates for Australia of the effects of changes in migration on the volume of inbound and outbound tourism. When supplemented with information about tourist spending, estimates can be made of any expenditure changes associated with migrationinduced tourism. Such migration-induced tourism expenditures will have economic impacts on the economy. This study estimates the economic impacts of migration-induced inbound and outbound tourism flows using a computable general equilibrium (CGE) model for Australia projecting the effects on key economic variables such as real GDP, real value added, economic welfare, and employment.
