I actually care more about the exchange rate with the pound, as I have to keep repaying my British loan even though I am in Aus. That can have a severe impact on my spending ability either from the US or at Aussie retail. So I'd actually rather we were stronger against the pound, and if that for some reason means a worse exchange rate with the dollar then so be it.

(At the moment we are still just above parity with GBP... parity is considered to be GBP2 to AUD1, because of course our wonderful British pound is better than your colonial currency... )
