doubts

Hold a few gold shares..but my doubt over the past few weeks is...as the fed keeps printing more dollars and pumping it into the economy...i guess somewhere down the line there will be hyperinflation in the US ..but what does it translate into for oz?
1) AUD strenghthens..?
2)Gold Booms..?
3)How will it create inflation in our local economy?
4) If the US economy crashes does it necesarily mean that Aus will follow...wont the local trade still continue?

Any economists /oldtimers out there with views? rgds
