I use Interactive Brokers to trade mainly Aussie shares and occasionally o/seas shares. Execution works fast and flawless and cheap.
You don't hold the shares directly which also initially concerned me but after some research which shows they are one of the biggest brokers around, been operating for many decades, profitable, listed on NASDAQ mcap of ~US$40B, stock near all time highs ie. risk of them going under is extremely low.
