I currently trade with Westpac. They offer international markets via partnership with Pershing (LSE over the phone only). Broker fees are USD$57.95 or 0.65%, whichever is greater. Commsec is USD $39.95 or 0.40%, whichever is greater. That's a significant difference if you are planning on holding long term and selling when the SP is many multiples what it currently is. Westpac also mentions a 63 buck annual fee for "inactive" accounts which is charged if no transactions are triggered during the calendar year. I'm assuming Commsec would be the same as it appears to be due to USA regulations where the trading would be triggered from.
I'm going to look into IG as their fees from first glance appear far superior.
