Murray-Darling fish kill: Greens accuse Coalition of hiding information from Senate

Sarah Hanson-Young says failure to release data about draining of Menindee Lakes 'stinks of a cover-up'

The Greens have accused the federal government of hiding critical information from the Senate on why the Menindee Lakes were drained twice in the last four years, as investigations get under way into what caused around 1 million fish to die.

Further fish kill events are expected later this week as temperatures soar to 45C in western New South Wales.
