Last month's huge rain event in New South Wales saw vast torrents pummel the land, in some cases, in areas that had already been savaged by the fierce 2019-20 wild fires.

Massive amounts of unstable soil has been swept away, draining into waterways, threatening river and wetland eco-systems and animal life, and wreaking havoc for farmers. Now, amid plans for salvage logging in some areas, there's a fight over whether areas that have been damaged by multiple natural disasters should be left alone altogether.
