Staying with Aussie developments, Japan's Kirin Holdings Co. said it is reviewing options including a possible sale of its substantial Australian dairy business.
Various corporate initiatives have coincided with tough times for Australian dairy farmers, who have struggled with drought and a difficult local consumer market, which is dominated by Coles and Woolworths.
Early this year, Canadian dairy giant snapped up Fonterra's Australian equivalent - Murray Goulburn - after the co-op suffered near crippling losses last year.
This month, the Australian Federal Court ordered former Murray Goulburn managing director Gary Helou to pay A$200,000 in penalties for being knowingly concerned in Murray Goulburn's false or misleading claims about the farmgate milk price it expected to pay dairy farmers during the 2015-16 milk season.
As part of the resolution of the proceedings, Helou gave an undertaking to the court that he would not be involved in the dairy industry for three years.
