FWIW: Etrade starts their global trading unit and I funded it today. Previously, you had to buy the pinksheet equivalent which may lack volume compared to canadian counterpart for instance. Doesn't include AU, but has Euro, Can, Japan, Hong Kong and British Pound. You have to convert your US$ to currency of stock so I am sure you are paying an exchange fee. If you are an etrade customer you can open this additional acct online and it is linked to your others. Otherwise you have to mail in an app. with original signature. The problem is you have to fund it independently, you cannot transfer your brokerage acct into it and you can't do an IRA or Roth or Margin
My picks are my own and many times wrong, generally looking 3-6 months out
