'Triple whammy': drought, fires and floods push Australian rivers into crisis

The combination of extreme weather events will have cascading impacts on fish, platypus and invertebrates, threatening some with extinction

Australia's rivers are being hit by a "triple whammy" of impacts that will have serious and long-term effects on species and could push some to extinction, according to experts.

Drought, bushfires in river catchments and now widespread heavy rain in the east of the country have created a cascade of impacts on fish, invertebrates and platypus.
