As title, it seems the front runners are IBKR & Schwab, going through recent posts here it seems many are recommending Schwab over IBKR for their $0 brokerage fee but it seems they have a 1% currency conversion rate compared to IBKR of 0.02%, seems like a no brainer IBKR would be better in the long run if you're having to covert your AUD to USD to purchase shares?
Am I missing anything or are there any other broker platforms that you would suggest?
You can deposit to Wise to convert to USD, and then to Schwab.
