It seems to me that there are significant global shareholders here.
Citicorp Nominees Pty Limited 67,609,144 10.89%
HSBC Custody Nominees (Australia) Limited 45,363,008 7.31%
BNP Paribas Nominees Pty Ltd 45,572,917 7.34%
These are all multinational banks eg. BNP Paribas is the French National bank with a couple of trillion in assets, i worked for them decade ago. (look them up) If these guys are interested, somethings cooking.
