I live in Australia by the way. I'm British though. The reasearch was done by the World Health Organisation apparently.
Here's a slightly shitty link to an article

That is absolutely worrying isn't it? I feel quite shocked really. When we moved here three years ago, I was nervous as I was convinced it was a very sporty country...full of fit people!
There are, it seems to me, a lot of very big young people though. And I now see more overweight OLDER people than ever. When I was younger, (I am 44) old people were bird-like...tiny and thin...they'd seen wars etc.
Now they're all the baby boomers and a lot of them are very large.
It worries me...my DC are both slim but what if that changes? We do eat well and exercise....but EIGHTY percent!??? It seems so many!
