"have you converted the UK dollar to the aus dollar, in your statement ?
the UK dollar is about double Aus dollar...so the $450 K in the UK is about $900k Aus"

I think you will find once converted it's closer to about 690K rather than 900k. So quite a large discrepancy. As of a few weeks ago the exchange rate was closer to 0.70, once again quite a discrepancy to 0.50.
