Browsing through the comments on a Crikey article and found this, clearly a few people are aware of what's gone on. Not strictly correct, but anyway:
"you are right
Successive Australia governments have FAILED to stop this. They are all to blame.
The Chinese are sneaky. Look at Brockman Resources (BRM) a group of Chinese in the SAME office business bought just under the reportable 5%. They then grouped the shareholdings together and had around 55%. They are now trying to mop up.
The holding company of the vehicle they use runs limo’s. I kid you not.
ASIC were ASLEEP, investigated and could not prove the small 4.99% parcels from an address in the same office tower, was breaking our rules.
Where is Swan on this. Brockman own huge Iron Ore Reserves."
