An agricultural group called Monaro Farming Systems, associated with Energy Minister Angus Taylor's brother, has thanked the New South Wales Deputy Premier, John Barilaro for a one hundred and seven thousand dollar grant used to fund research to support efforts to water down protections of endangered grassland.

Mr Taylor has previously come under fire for approaching the then environment Minister, Josh Frydenberg, to discuss the possibility of weakening native grassland protections.

Barilaro is the local member for Monaro, where multiple members of Mr Taylor's family are extensive land owners.
