Interactive Brokers. The conversion is really easy - 1 ADR = 30 Shares. And since 1 USD = 1.03 AUD you can basically just take the price and divide by 30 to see what the ADR should be worth. Still, with such a extremely thin volume and wide bid-ask spread, you cannot really use the ADRs in a prudent manner.
Also the ADR is a terrible way to invest currently due to the insanely low volume and high bid-ask spread.Better to buy on the Australian stock exchange if you have access under Prr.ax . The drop was due to an article back when it was around .24 (on Australian exchange) bashingitfor a lofty valuation. I would argue now it is undervalued and am buying, but not the ADR.
