EDIT: actually, the Chase emails I got after they authorized my card show the amount in USD, not AUD. I'll probably know more once the Kickstarter finishes but according to Visa's exchange rates for 8/15, AU$1 = US$0.933107 and the authorization on Chase's online banking is for $0.93 so it's probably still a good bet that I didn't.
I think things will always appear as USD to Chase. You won't see the exchange rate until you can get a PDF of the statement, but it seems like using the current day's Visa exchange rate still works. ^
