Documents revealed to the Senate have shown officials in the Federal Department of Environment and Energy attempted to cover up the extent of the controversial $444 million grant to the Great Barrier Reef Foundation.

One document shows an email to colleagues from a Department Communications Manager describing the best way to refer to the grant, saying, “hopefully this will be too much bureaucratic detail for a journalist anyway”.

$100 million of the Great Barrier Reef Foundation grant will reportedly go to the Reef Resilience and Adaptation Program, which an institute within the Environment Department is co-leading.
