Program: What's driving the iron ore price plunge?

On today's program:

• Since May the price of iron ore has more than halved - It peaked at just over $230 US dollars a tonne, and it's now trading below $100 US dollars a tonne. Yesterday around $50 billion was wiped off the Australian share market off the back of the iron ore price collapse. Fortescue Metals Group's share price for example has gone from a high earlier this year of $26 to now around $14. There are now fears that one of China's biggest property developers 'Evergrande' could go under.

• In South Burnett, Queensland, one Aboriginal community is facing a growing mental health crisis. Cherbourg is losing an alarming number of young people to suicide, prompting calls for urgent action. A warning that some listeners may find this story distressing.

• In Coffs Harbour, New South Wales, one man's desperate plea for help on a social media post, has brought out the best in his local community. Reife Wallis expected a negative response after asking for assistance on a community Facebook page, but was instead greeted with offers of support like food, blankets and other essentials. While social media can be notorious for trolling and cruelty, in this instance, Mr Wallis was given life-saving help that he will forever cherish.

• Every day, some 26 million cattle in Australia are creating an estimated 80 million tonnes of livestock dung every year. Before exotic dung beetle species were introduced, rock hard dry cow pats fouled pastures, polluted creeks and dams during rain events and provided the perfect breeding ground for flies and parasites. As part of a $23 million research project, Dr Russ Barrow from Charles Sturt University has been conducting dung beetle workshops around the country.
