I've got some Aussie notes from my last trip in my drawer here. They are indeed plastic. They even have a little clear window in them you can see right through.

I've got some Aussie notes from my last trip in my drawer here. They are indeed plastic. They even have a little clear window in them you can see right through. I'd never really thought about it until now. I don't know if they last longer or not because already some of the ink/paint is rubbing off the 2009 vintage $50 where it gets folded. Edit: Here you go: they are polypropylene polymer. Wild http://www.travel-australia.org/money.html http://www.travel-australia.org/money.html
