These things tend to move in cycles, of course, but for the foreseeable future, the direction for the $US is down. Not straight down, of course, but the trend is downward, nevertheless.
If I had traveled to the US from Oz to buy a boat, being forced to exchange $AU into $US to make the purchase
when the exchange rate favored the $US, I wouldn't compound that unfortunate event by sailing the boat around the world, then re-selling it in the US when the $US I'd receive at the close would buy many fewer $AU. If I were in that position, I'd keep right on going back to Oz and sell the vessel there.
None of the above may apply to you, Mark, and it may well be that you have no intention of selling Sea Life
at any time. I'm just pointing out that any $US that someone exchanges into almost any other currency, presently, will not go very far. The only reason to make such an exchange now is, 1) because one has to, and, 2) because it will probably only be worse the longer one waits.
