The NSW Greens have called for a royal commission into the management of the Murray-Darling Basin, as clean-up begins in outback NSW after the biggest fish kill in the region's history.
Millions of dead fish have washed up on the Darling-Baaka River at Menindee and towards Pooncarie, near the borders of Victoria and South Australia, after prolonged flooding and repeated heatwaves in recent weeks.
