Answer:
Australia - Shift​ Australia's production function​ upward, create a movement up along the production function as the​ full-employment quantity of labor​ increases, and increase potential GDP
United States - Will not change potential GDP as production happens in Australia
Explanation:
Australia's production potential will rise which will be depicted by a shift upwards in the Production Possibilities Frontier (PPF) thereby leading to an increase in the full employment quality of labor and potential GDP for Australia.
As the production is happening in Australia, it will not affect potential GDP in the US.
