A Shooters, Fishers and Farmers MP has raised eyebrows in the New South Wales Parliament by suggesting he ate an elephant he shot.

Photos of Robert Borsak shooting an elephant on a trip to Africa more than a decade ago have previously made headlines and sparked outrage from animal activists.

While giving a late-night speech to Parliament railing against extreme animal rights groups, Mr Borsak began defending the rights of humans to eat meat.

"Humans have a right to eat meat if they choose to do so, it's as simple as that," Mr Borsak said.

"I choose to hunt and gather my own meat because it is my right to do so, it's a clean, organic and sustainable way to live.

"I choose to cull feral and invasive animals because culling protects our native species and habitats, and consider myself a responsible and ethical hunter and fisher."

Greens MP Jeremy Buckingham interjected, asking : "Did you eat the elephant?"

Mr Borsak replied that he had.

Mr Buckingham said the revelation was disgusting.

"It's sick to shoot and kill an elephant for thrills, and it's revolting that Mr Borsak would eat the elephant," Mr Buckingham said. "He's unfit for office."

'Buckingham ate Borsak's hunted venison at BBQ'

A spokesman for the Shooters, Fishers and Farmers party said the hunting trip in question took place before Mr Borsak was elected to the Legislative Council.

"The meat from Mr Borsak's hunting trip was offered to the traditional owners of the land as a mark of respect, on top of other fees paid," the spokesman said.

"We are surprised at Mr Buckingham's hypocrisy, given that he was more than happy to eat Mr Borsak's freshly hunted venison sausages at a NSW Parliament House BBQ raising money [for a children's hospital].

"Mr Buckingham happily went back for seconds and thirds and we are still waiting for his gold-coin donation."
