From the AFR:
Veteran political commentator Laurie Oakes, writing in News Corp tabloids at the weekend, said that “several” applications had recently been lodged with the Foreign Investment Review Board that would affect mining companies. The applications “raise the possibility of significant upheaval in the iron ore industry and ownership of sections of it over the next 12 months”, Mr Oakes wrote.
…A government source said the level of activity could not be described as a flurry, although it was “interesting”. It is believed the applications being submitted relate to on-market activity, not to a wholesale takeover in the iron ore sector.
