If you have an Australian trading account you can have it enabled for international trade if you want.. there is a slight price premium for doing it and the trades are slightly more expensive.Oh ok, so you can get them in Aus? Or not really?
BTW the min trade is dictated by the trading platform, not the company. With commsec min trades are $500.
When a company says "min investment $XXX" that is when they are doing a capital raising direct to existing shareholders or an IPO (these are normally done outside of the trading platform and don't incur brokerage fees).
