Non resident trading accounts, page-2

Non-residents can already open a SWF account and trade... The best way is establishing an Australian company (Non-residents can do this. Google it.)
There are also multiple companies that could establish the company for you, taking care of everything including virtual office address and phone, local director, documentation for bank account, bookkeeping etc.
Then open your Selfwealth account in your Australian company's name. Don't forget to pay your taxes. Trade away

Complete setup inc. fees should be around $1500, but if you use a lawyer: $5000+
