"I am not sure why you would be angry, because it's your national team. You'd be disappointed, 100 per cent.
"I have certainly had some of my own hate mail to deal with.
"I am not sure how they get my email address ... or (my) phone number.

Cheika said he "loved" the fact that few outside Camp Wallaby give them much of a chance in Saturday's second Test at Forsyth Barr Stadium.
"I know it's a tough situation and I am sure we have had a lot of stones thrown at us, and justifiably so in some areas," he said.
"But I love it in that space. That's where I have lived most of my life.
"I want the players to enjoy it, and then get out of it and then stay hungry when you do.
"I think it's a really great opportunity for us - and I am not just saying that because that's the spin everyone likes to put on when you're in that (situation).
"This really is a huge opportunity for players to show who they really are."
