The problem with that is that the Government would then be in breach of the WTO treaties it signed in the hope of a level playing field.
Our various Governments used to have such policies but they had to be rescinded.
But one may suggest that most of us on this very forum are in breach of what we are suggesting our Government should be doing. On that note I must say that 3 of my vehicle were at least Australian assembled and one almost completly Australian manufactured, but that happened in the heyday of Australian manufacturing.
