Can this be circumvented if it got sent to Australia first and from there to the States? Obviously, there is an additional cost. Or is Australia going to get hammered with 145% tariffs?
If you were to buy a bunch of components from China, have them shipped to Australia and assembled there, then shipped to the US, you would pay the tariff applied to Australia, not China. Of course, you probably are paying some sort of import tax when the components make their way into Australia too.
