South Australian correspondent Peta Doherty toured the Pike Floodplains in the Riverland with Indigenous rangers from River Murray and Mallee Country.

Weeks of above-average temperatures have taken a toll on the Great Barrier Reef, as scientists confirm at least two-thirds of the reef is experiencing another mass bleaching.
