Cape Town - Wallabies coach Michael Cheika told reporters he has been on the receiving end of numerous hate mail messages following the test against the All Blacks this past weekend.
The abuse began to gain attention in June when Cheika had to phone a Wallabies fan who posted a rant on Facebook that went viral.
"I have certainly had some of my own hate mail to deal with," Cheika told the Sydney Morning Herald. "I am not sure how they get my email address but they happen to, or a phone number. But you have to roll with that stuff mate, you have to deal with it.
"There's only one way that can change. Nothing that happens from Monday to Friday. The only way these things change is on the field."
Cheika also pleaded with supporters to stay positive.
"No one should be angry," Cheika said. "People can be disappointed. Anger is a different emotion and I have heard a lot of anger and stuff around from people who might be bitter about it or whatever.
"I am not sure why you would be angry because it's your national team. You'd be disappointed, 100 per cent.
"As Wallabies, we have to change that on the field and that's the only place to do it."
