On reflection I don't think exchange rates are any sort of show-stopper.
I either agree on an exchange rate with the client ahead of time and do
a forex deal without a rate (and wear the loss or gain when actually
exchanged) or bill in AUD and expect AUD to be remitted. I don't think I
want the complication of the MoneyField doing what someone else thinks
should happen.
Agreed. Currency exchange happens at the financial institution, not in our web apps. It would only be useful for estimation in my mind (I see no need for it in my application so haven't thought much about it).

But py-moneyed does claim a complete dictionary of ISO 4217 currencies.
https://github.com/limist/py-moneyed/blob/master/moneyed/localization.py only has the localisation configured for a handful of currencies, and not our precious AUD :). The shortest party would be adding them all in or doing https://github.com/limist/py-moneyed/issues/22
It also supports Python 2.7 which is useful for me because I haven't yet
rebuilt apache/mod_wsgi for py3 on my Ubuntu VMs. I wish there was a
pill to cure procrastination.
Work with what you've got (that being procrastination): http://www.structuredprocrastination.com
poswald/python-money does the same and looks interesting. Might go there
and see how it works. It also has form and field helpers.
