Re: Cash passports or alternative - Debit cards might still rule
I think you miss the hidden cost with cash passports, the poor initial exchange rate. The banks sell at the same rate as for selling cash notes, this is about 4-6% below the mid rate, and they then hit you another 1% fee. You can see the big difference between the buy and sell rates.
So if a credit card or standard debit card get you for a 3% fee at least the mastercard exchange rate is close to the midrate.Of course you really should use a 28degrees card.
[My Note: ANZ have a slightly different (higher) rate for loading Travelcards/t-cheques (although CBA is the same as notes) but this really covers the 1.1% higher rate to load].
I have read the ensuing posts with interest (and although I have actually read the fine print despite assertions to the contrary :mrgreen

have since checked out the 28 degrees card as well, which I hadn't in detail before, as I can still get one before I go to Europe for 6 wks at the end of May if I need to. Hardly need another CC given I have QFF Visa/Amex + M'card already, but if it is great as everyone says...
The difficulty one would have to generally say is second-guessing forex movements. With 28 Deg. and all other CC's you simply chomp on it and have to pay whatever the rate is on the day the charge is converted. OK with 28 Deg. you no doubt are fee free in terms of rate addons (rather than 3-3.5% with other banks) with a supposedly Christian rate, but can anyone tell me exactly and accurately what this mysterious "mid-rate" is? Is it literally half way between the cash notes buy and sell rate, or between IMT/TT buy/sell rates (for the latter ANZ USD rate for Thurs. for IMT/TT is 1.1142 and 1.0551) - so for today the "mid-rate" is notionally 1.085? I am not aware from among the 3 rates that ANZ offer- IMT/TT, Travelcard/cheques and notes which one is actually applied to CC transactions - is it all secret banker's business?
I do my own crude form of hedging by starting watching the currency rates (which I check every day on my Ipod - Xe.com & ANZ) 2 months or so before I go on a planned holiday. That way I know that if the Euro has gone from 0.69 thru 0.73 I know what is relatively the best day to buy and lock it in.
The elephant in the room I have since reflected upon is: if you are purely transacting in the US on your o'seas jaunt at the moment you cannot lose it seems, with the AUD heading for the headline figure of 1.10USD. However if you are in the Eurozone etc and you are first converted to USD then to AUD surely you are doing yourself even more damage, due to weak USD/strong AUD, than the usual extra cost of a double exchange rate switch? I saw a telling graph on TV tonight with AUD going up 4% over X period against the Euro with the USD going down 15% during the same period. Did not sound like such a good look converting thru USD as the median currency to me at all. Think I might revert to my original plan to buying my Euros on a 'good' day on Travelcard at fixed rate rather than seeing conversions sink under the waves with the USD conversion.
Do Visa/Mastercard foreign transactions all convert thru USD? I assume my Euro Travelcard, if used in non-EUR Czech/Hungary etc, will simply be converted to Euros rather than thru another currency. Economics professors, start your engines!
