Yes it seems that's OK, their personal banking booklet says on pg.
29 that for non-AUD payments into the Everyday Global account
"Transactions can be settled in the same foreign currency", for
supported currencies.
But I followed up the references I read to transferring USD out of
non-US PayPal accounts and it's not quite as simple as I thought.
The PayPal user agreement actually says you can transfer US Dollars
to a US bank account. So the foreign currency accounts won't work
because they're still Australian accounts. I'd need an actual bank
account in the USA.
I saw the links you posted about how to get one of those, but since
I haven't got any connection or travel plans to the USA, it looks
pretty tricky opening a US bank account from Aus.
On the Wise page:
"Can you open a US bank account from overseas??
It is possible in theory to set up a US bank account online from
abroad -- but in practice it's usually hard to find a traditional
bank which will let foreigners get full access to an account online.
That may mean you can start your application remotely, but need to
attend a branch to get verified, for example." ...

Also I see now that PayPal charge a 3% fee for Australian USD
transfers to a US bank, which is about the same fee that I get
charged for converted USD payments out of the AUD bank account I
use for that at the moment, although I would at least avoid the
currency conversion fees from PayPal and the debit card company.

Overall it looks like more work and less benefit than I
anticipated, so I think I'll give up there, but at least now I
know.
