Quade Cooper's grandmother said the Wallabies' shocking loss to Ireland on Saturday night was because the team "didn't gel well".
But win or lose, Millie Cooper said she was still proud of her grandson - no matter what.
Cooper, dubbed Public Enemy No 1, was greeted with boos from the crowd during the match against Ireland at Eden Park.
Mrs Cooper, 76, of Kaikohe, said her grandson had been treated unfairly by New Zealanders after he chose to play for Australia.
"I just want them to leave him alone so he can focus on his game," she said.
